2. Read and understand the warnings posted
on the machine and in this manual. Failure
to comply with all of these warnings may
cause serious injury.
3. Replace the warning labels if they become
obscured or removed.
4. This band saw is designed and intended for
use by properly trained and experienced
personnel only. If you are not familiar with
the proper and safe operation of a band
saw, do not use until proper training and
knowledge have been obtained.
5. Do not use this band saw for other than its
intended use. If used for other purposes,
Walter Meier (Manufacturing), Inc., disclaims
any real or implied warranty and holds itself
harmless from any injury that may result
from that use.
6. Always wear ANSI approved safety
glasses/face shields while using this band
saw. Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.
7. Before operating this machine, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Remove all
loose clothing and confine long hair. Non-
slip footwear or anti-skid floor strips are
recommended.
8. Wear ear protectors (plugs or muffs) during
extended periods of operation.
9. Some dust created by power sanding,
sawing, grinding, drilling and other
construction activities contains chemicals
known to cause cancer, birth defects or
other reproductive harm. Some examples of
these chemicals are:
•Lead from lead based paint.
•Crystalline silica from bricks, cement
and other masonry products.
•Arsenic and chromium from chemically
treated lumber.
Your risk of exposure varies, depending on
how often you do this type of work. To
reduce your exposure to these chemicals,
work in a well-ventilated area and work with
approved safety equipment, such as face or
dust masks that are specifically designed to
filter out microscopic particles.
10. Do not operate this machine while tired or
under the influence of drugs, alcohol or any
medication.
11. Make certain the switch is in the OFF
position before connecting the machine to
the power supply.
12. Make certain the machine is properly
grounded.
13. Make all machine adjustments or
maintenance with the machine unplugged

7.4 Vertical cutting plate
These steps are only necessary when using
band saw in vertical position.
1. Disconnect machine from power source.
2. Open valve on hydraulic cylinder (lever
parallel to cylinder) and raise bow to vertical
position.
3. Remove two screws and remove seat plate,
as shown in Figure 5.
Figure 5
4. Guide blade through slot in vertical cutting
plate (F, Figure 5), and tighten with the two
screws.
5. Verify that vertical cutting plate is square to
blade, using a machinist’s square on the
plate and against the blade (Figure 6).
6. If adjustment is needed, loosen screws and
place shims where required. Tighten screws.
Figure 6
7. Place a level on vertical cutting plate (Figure

Figure 8
7.5 Vertical support post
This is mounted to rear of band saw to help
stabilize saw when bow is in vertical position. It
is generally not needed when bow is set for 90°
cuts before raising it to vertical. However, if
operator raises bow that was set for
mitering, the band saw can tip over. The
support post must be installed to prevent this.
To avoid tipping risk,
remember to set bow at 90-degree cut angle
before raising to vertical position.
Mount post with two screws and washers to rear
of saw, as shown (Figure 9).

7.6 Coolant system
Make sure there is coolant in
the tank before operating, to prevent damage
to pump.
Use of a water-soluble coolant will increase
cutting efficiency and prolong blade life. Do not
use black cutting oil as a substitute.
1. Remove coolant return hose (A, Figure 10)
from filter cup, and slide tank out of saw
base.
2. Fill tank to approximately 80% of capacity.
Full capacity is 9 liters (2.5 gal).
3. Place tank into base. Place coolant return
hose into the filter cup. Verify that opposite
end of coolant return hose is connected to
the coolant pan.
4. The coolant supply hose (B, Figure 17)
should connect to the two valves on the
blade guide assemblies.
Figure 10
8.0 Electrical connections
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
The HVBS-710SG Band Saw is rated at
115/230V power, and pre-wired for 115 volt. The
band saw comes with a plug designed for use
on a circuit with a grounded outlet that looks like
the one pictured in A, Figure 11.
Before connecting to power source, be sure
switch is in off position.
It is recommended that the band saw, when
operated at 115 volt, be connected to a
dedicated 20 amp circuit with a 20 amp circuit
breaker or time-delay fuse rated “D”. It is
recommended that the band saw, when
operated at 230 volt, be connected to a
dedicated 15 amp circuit with a 15 amp circuit
breaker or time-delay fuse rated “D” Local
codes take precedence over recom-
mendations.
8.1 Grounding instructions
1. All Grounded, Cord-connected Tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having anequipment-grounding conductor and a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit
the outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes is the equipment-
grounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified
electrician or service personnel if the
grounding instructions are not completely
understood, or if in doubt as to whether the
tool is properly grounded. Failure to comply
may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-
prong grounding plugs and 3-pole receptacles
that accept the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
less than 150 volts:
This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated in A,
Figure 11. An adapter, shown in Band C, may
be used to connect this plug to a 2-pole
receptacle as shown in Bif a properly grounded
outlet is not available. The temporary adapter
should be used only until a properly grounded
outlet can be installed by a qualified electrician.
This adapter is not permitted in Canada.
The green-colored rigid ear, lug, and the like,
extending from the adapter must be connected

12
to a permanent ground such as a properly
grounded outlet box.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated in D,
Figure 11. The tool has a grounding plug that
looks like the plug illustrated in D. Make sure the
tool is connected to an outlet having the same
configuration as the plug. No adapter is
available or should be used with this tool. If the
tool must be reconnected for use on a different
type of electric circuit, the reconnection should
be made by qualified service personnel; and
after reconnection, the tool should comply with
all local codes and ordinances.
Figure 11
8.2 Voltage conversion
1. To switch the incoming power leads for 230
volt operation, follow the wiring diagram on
the inside cover of motor junction box.
Similar diagrams are shown in Figures
12/13.
2. The plug on the end of the motor cord must
be replaced with a UL/CSA listed plug rated
for 240V.
3. Change the wiring inside the junction box of
the coolant pump, according to the diagram
found there.
Figure 12
Figure 13
8.3 Extension cords
The use of extension cords is discouraged; try to
position equipment near the power source. If an
extension cord becomes necessary, make sure
the cord rating is suitable for the amperage
listed on the machine’s motor plate. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Use Table 1 as a general guide in choosing the
correct size cord. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the heavier the cord.

9.0 Adjustments
The settings on your band saw, such as blade
squareness and tracking, were carefully
performed by the manufacturer. You should,
however, verify these before operating, in case
misalignment has occurred during shipping.
9.1 Squaring blade to table
1. Disconnect machine from power source.
2. Place machinist’s square (A, Figure 14) on
table and against blade.
3. Check to see that blade contacts the square
along entire width of blade.
4. If adjustment is needed, loosen screws (B,
Figure 14) and rotate blade guide
assemblies until blade makes contact with
square along its entire width.
5. Tighten screws (B).
NOTE: If adjustment of squaring blade to table
was necessary, re-verify all other blade
adjustments.
Figure 14
9.2 Squaring blade to vise
1. Disconnect machine from power source.
2. Place a machinist’s square (A, Figure 15) on
the bed against the blade and the fixed vise
jaw. The square should lie along entire
length of jaw and blade without a gap.
3. If adjustment is necessary, loosen screws
holding vise (C, Figure 15) and shift vise
until it aligns with square.
4. Retighten screws.
Figure 15
9.3 Vise positioning
Keep hands away from blade
while adjusting vise. Do not make any
adjustments to vise while the machine is
running.
The vise has a quick-release feature which
allows fast positioning of the floating jaw against
the workpiece, and then a final tightening with
the handwheel.
1. Make sure fixed jaw (D, Figure 16) has been
squared (section 9.2, Squaring blade to
vise).
2. Position workpiece against fixed jaw.
3. Loosen hexagonal stud (E) on floating jaw.
4. Rotate handwheel (F) slightly counter-
clockwise, then push floating jaw by hand
until it contacts workpiece and adjusts to its
shape.
5. Tighten stud (E).
6. Use handwheel to tighten the clamping
pressure.
The quick release function can also be used to
quickly disengage floating jaw when the cut is
finished.
Figure 16

9.4 Miter cuts
1. Loosen handle (G, Figure 17).
2. Rotate bow to desired angle up to 45-
degrees, using scale indicator on front of
base.
3. Tighten handle.
Figure 17
The angle scale is sufficient for most mitering
operations. If greater precision is needed, verify
setting with a protractor.
If handle (G) movement is obstructed, lift up on
handle and rotate it on the pin. Release handle,
making sure it seats itself properly on pin.
Bow should be returned to
90-degree cut angle before lifting into
vertical position. See section 7.5.
9.5 Setting feed rate
The feed rate of the blade into the workpiece is
important to band saw performance. Excessive
pressure of blade against the workpiece may
break the blade or stall the saw. In contrast,
insufficient pressure rapidly dulls the blade.
The hydraulic cylinder resists movement of the
bow in the downward direction. It offers no
resistance when the bow is raised upward.
To increase feed rate, turn dial (A, Figure 18)
counterclockwise. To decrease, turn clockwise.
To close hydraulic flow, turn lever (B) down,
perpendicular to cylinder, as shown in Figure 18.
To open hydraulic flow, raise lever (B) parallel to
cylinder.
Feed rate is adjusted by the operator until the
saw is operating efficiently; usually determined
by observing chip formation. See section 11.4,
Evaluating cutting efficiency.
Figure 18
9.6 Counterbalance spring
The counterbalance spring helps control the
amount of weight the saw bow puts on the
workpiece when the hydraulic control valve is
fully open. The hydraulic cylinder will not
compensate for improper counterbalance.
If the spring is not set properly, one can expect
poor performance, crooked cuts, tooth stripping,
stalling, and/or the blade running off the wheels.
Spring tension has been set by the
manufacturer, and should not require
adjustment. If future problems arise, indicating
improper counterbalance, adjust spring as
follows:
1. Disconnect machine from power source.
2. Turn ON hydraulic cylinder valve and place
saw bow in horizontal position.
3. Turn feed rate valve on hydraulic cylinder
counterclockwise until it stops.
4. Place a weigh scale (such as a spring or
hanging scale) beneath blade tension
handle, and lift saw bow. Scale should
indicate approximately 5 to 6 kg (11-13 lb).
5. If adjustment is needed, loosen one nut and
tighten the other (H, Figure 17) on the eye
bolt, until scale indicates 5 to 6 kg.
9.7 Blade installation/replacement
This band saw is designed
for use with blades that are 3/4" wide by
0.032” thick x 93” long. Use of blades with
different specification may cause inferior
performance.
A general-use variable-tooth blade is provided
with this band saw.
The choice of blade pitch is governed by the
thickness of the work to be cut: the thinner the
workpiece, the more teeth advised. A minimum
of three teeth should engage the workpiece at all
times. If the teeth of the blade are so far apart

15
that they straddle the work, severe damage to
the workpiece and to the blade can result.
1. Disconnect machine from power source.
2. Raise bow to vertical position, and secure in
place by turning off hydraulic cylinder.
3. Remove red blade guard (A, Figure 19) by
removing two screws.
Red blade guard must be
reinstalled after new blade is fitted.
Figure 19
4. Remove brush assembly (B, Figure 19) by
removing two screws.
5. Loosen blade tension by turning handle (C,
Figure 20) counterclockwise.
Figure 20
6. Open back cover by loosening two lock
knobs (D, Figure 20).
7. Carefully remove old blade. NOTE: Leather
gloves are recommended when handling
saw blades.
8. Install new blade first between bearing
guides. Make sure blade teeth face same
direction as shown on the blade direction
label on saw. (If teeth still point in wrong
direction despite mounting blade properly,
the blade has been turned inside-out. Twist
blade right side-out and reinstall.)
9. Position blade around wheels, making sure
it rests near the flange on both wheels.
10. Tension blade using handle. Do not over-
tension. See section 9.8, Blade tension.
11. Close back cover and secure with knobs.
12. Install red blade guard, and brush assembly.
13. Connect machine to power source.
14. Run machine to verify that blade is tracking
properly. See section 9.9, Blade tracking.
9.8 Blade tension
Disconnect machine from
power source, and use caution when
working with sharp blade.
Blade tension is vital to achieving proper results
from the band saw. For shipping purposes, the
blade may not be at full tension – verify tension
before operating.
Proper blade tension is 1550 to 1760 kg/cm
2
(22000-25000 lb/in
2
) as measured on a blade
tension gauge (not provided).
To set tension without the use of a tension
gauge:
1. Disconnect machine from power source.
2. Install blade between wheels and between
bearings on blade guides.
3. Lightly tension blade to remove any sag by
turning handle (C, Figure 20) slightly
clockwise.
4. Turn tension handle (C, Figure 20) 1-3/4 to
two revolutions clockwise.
Do not overtighten blade;
this may cause it to stretch or warp.
5. Close covers, connect to power source, and
run saw for 2 to 3 minutes to allow blade to
seat properly.
6. Disconnect machine from power source.
Open cover and loosen blade until it just
begins to sag.
7. Tighten blade until it straightens between
blade wheels and all sag is eliminated.
8. Tighten blade by turning handle (C, Figure
20) two full revolutions.
Do not overtighten blade;
this may cause it to stretch or warp.
TIP: Slacken blade tension when finished with
operations, to prolong blade life. Make note of
indicator position on tension label (E, Figure 20)

16
for quickly returning tension to its previous
setting.
9.9 Blade tracking
Tracking the blade requires
that the band saw be operating while the
back cover is removed. This adjustment
should be performed by qualified persons
only.
Blade tracking has been tested at the factory.
Adjustment is rarely required when the blade is
used properly and if the blade is correctly
welded. If a tracking problem occurs, first
inspect blade condition, then adjust tracking as
follows:
1. Raise bow to vertical position and secure by
turning off hydraulic cylinder valve.
2. The blade should be properly tensioned.
Refer to section 9.8 Blade tension.
3. Open back cover.
While performing the
following steps, keep the blade from rubbing
excessively on wheel flange. Excess rubbing
will damage wheel and/or blade.
4. Start saw and observe blade movement.
Blade should run next to, but not tightly
against, wheel flange.
5. If blade will not track in position, loosen
screws (F, Figure 21), but do not remove.
Figure 21
6. Turn set screw (G, Figure 21) counter-
clockwise so that blade starts to move away
from the flange; then immediately turn set
screw in the other direction so that blade
stops, then moves slowly back toward
flange. NOTE: This adjustment is sensitive;
do it gradually and in small increments
allowing the wheel to respond to the
changes.
Keep fingers clear of blade
and wheel to avoid injury.
7. Turn set screw to stop shifting of blade on
the wheel as it gets closer to wheel flange.
Put a six-inch length of paper between blade
and wheel. The paper should not be cut as it
passes between wheel flange and blade.
8. Turn set screw a small amount. Repeat the
insertion of paper between wheel flange and
blade until paper is cut into two pieces.
NOTE: You may have to repeat the check
with the paper several times before the
blade and the flange cut the paper into two
pieces. Do not hurry the adjustment.
Patience and accuracy here will pay off with
better, more accurate, quieter cutting and
longer machine and blade life.
9. When the paper is cut, back off the set
screw slightly. This assures that the blade is
not touching the flange of the wheel.
10. Tighten two screws (F, Figure 21).
9.10 Test cutting to verify adjustment
Test cuts can be used to determine whether or
not you have adjusted the blade accurately. Use
2-inch round bar stock to perform these test
cuts, as follows:
1. With bar stock securely clamped in the vise,
make a cut through the bar stock. (See
Figure 22.)
2. Mark the top of the bar stock.
3. Move the bar stock about 1/4-inch past the
blade so that you can begin a second cut.
4. Rotate the bar stock 180 degrees so the
mark you made is now at the bottom of the
cut.
5. Make a cut through the bar stock.
6. Use a micrometer to measure the thickness
variation of the disk you have cut from the
bar stock. Measure at top and bottom of
disk.

17
Figure 22
The saw blade can be considered correctly
adjusted when the variation measure is no more
than 0.012 inch across the face of the disk.
If you do not have a piece of 2-inch bar stock
available for a test cut, use a larger diameter
test piece rather than a smaller one. The
maximum thickness variation on any test piece
should be no more than 0.003 inch, per side, per
inch of stock diameter.
9.11 Setting blade speed
1. Turn machine OFF.
2. Turn lever (Figure 23) to desired setting:
#1 – 150 sfpm
#2 – 210 sfpm
#3 – 250 sfpm
Do not change blade speed
during cutting operation.
Figure 23
Material chips or shavings are the best indicator
of proper blade speed and downfeed rate. See
section 11.4, Evaluating cutting efficiency.
9.12 Blade guide adjustment
1. Loosen knobs (A, Figure 24).
2. Slide guide assemblies as close to
workpiece as possible, without interfering
with the cut. This will prevent excessive
blade exposure, and deflection of blade
during cutting.
3. Retighten knobs.
Figure 24
The guide bearings come pre-adjusted from the
factory, but should be inspected frequently and
adjustments made as needed.
For most efficient operation and maximum
accuracy, provide 0.001” clearance between the
blade and the guide bearings. The bearings will
still turn freely with this clearance. If the
clearance is incorrect, the blade may track off
the drive wheel.
1. Disconnect machine from power source.
2. Raise bow to vertical and secure in place by
turning off hydraulic cylinder.
3. Loosen socket head cap screw (B, Figure
25) and adjust guide assembly until back
roller bearing (C) is slightly contacting back
edge of blade.
4. Loosen nut (D) and rotate eccentric shaft (E)
to adjust side bearing until bearing just
touches side of blade. Do not pinch the
blade.
5. Blade should still move up and down freely
when grasped as in Figure 26. Make sure
blade teeth do not interfere with guide
bearings.
Make sure power is
disconnected and hands are protected
before handling blade.

18
6. Tighten nut (C).
7. Repeat for other blade guide assembly.
Figure 25
Figure 26
9.13 Chip brush
The chip brush (B, Figure 19) must be properly
adjusted and maintained in working condition;
otherwise damage to blade can occur. Adjust
the brush so that its bristles overlap the blade.
Replace brush if it becomes worn or damaged.
9.14 Limit switch
The stop screw (F, Figure 27) activates a limit
switch to shut off the saw when it reaches down
position.
The stop screw has been set at the factory. If
future adjustment is needed, loosen the hex nut
and rotate the screw, then retighten the hex nut.
Figure 27
10.0 Operating controls
To start saw, push On button (A, Figure 28).
To stop saw before it reaches the end of cut,
push Off button (B). The saw will automatically
stop at the end of a cut.
The Emergency Stop (C) shuts down all
functions on the band saw. The machine will not
start if the emergency stop is still engaged. To
start the machine, turn the emergency stop
button until it disengages
The flow of coolant to the blade area is
controlled by the valves (D).
Figure 28
IMPORTANT: When cutting magnesium, never
use soluble oils or emulsions (oil-water mix) as
water will greatly intensify any accidental
magnesium chip fire. See your industrial coolant
supplier for specific coolant recommendations
when cutting magnesium.

19
11.0 Operation
11.1 Pre-Operation inspection
Give machine an overall inspection and verify
the following:
1. Guards and covers are in place and in
working order.
2. Blade tooth direction matches diagram on
bow.
3. Blade is properly tensioned, and tracking
correctly on wheels.
4. Side and rear blade guide bearings are
properly adjusted.
5. Coolant level is sufficient.
6. Saw is properly lubricated.
7. Do not begin cut on a sharp edge; file edge
first.
11.2 Blade break-in procedure
New blades are very sharp and, therefore, have
a tooth geometry which is easily damaged if a
careful break-in procedure is not followed.
Consult the blade manufacturer’s literature for
break-in of specific blades on specific materials.
However, the following procedure will be
adequate for break-in of JET-supplied blades on
lower alloy ferrous materials.
1. Clamp a round section workpiece in the
vise. The workpiece should be 2 inches or
larger in diameter.
2. Set the saw on low speed. Start the cut with
a very light feed rate.
3. When the saw has completed 1/3 of the cut,
increase the feed rate slightly and allow the
saw to complete the cut.
4. Keep the same hydraulic cylinder setting
and begin a second cut on the same or
similar workpiece.
5. When the blade has completed about 1/3 of
the cut, increase feed rate. Watch the chip
formation until cutting is at its most efficient
rate and allow the saw to complete the cut
(see section ---, Evaluating Blade
Efficiency).
6. The blade is now ready for regular service.
11.3 General operating procedure
1. Raise bow until it will clear workpiece by a
few inches, and close hydraulic cylinder
valve to secure it in place.
NOTE: Never start a cut with blade
contacting workpiece.
2. Place workpiece in vise and tighten vise.
The workpiece should be fitted directly
between the jaws without adding other
objects.
When workpiece to be cut is a profiled
section, flat piece or special shape, refer to
examples in Figure 29 for proper clamping
positions. The top row shows acceptable
clamping positions; the bottom row shows
unacceptable positions.
If thickness of profiled section is very thin, a
piece which duplicates the profile should be
fitted inside the workpiece itself, to prevent
workpiece being crushed between the jaws.
Figure 29
Never hold a workpiece by
hand when cutting it – the workpiece should
be firmly secured in the vise. Do not reach
into the cutting area during cutting
operations.
3. Position work stop if needed.
4. Position blade guides as close to workpiece
as possible.
5. Move speed setting handle to desired
position. Do not move speed setting
handle during a cutting operation.
6. Set a suitable downfeed rate for that
operation on the hydraulic cylinder dial.
7. Push start button to begin blade rotation.
Allow blade to reach full speed before
beginning cut.
8. Turn on coolant flow. Adjust flow valves as
needed.
9. Open valve on hydraulic cylinder to allow
bow to descend in a gradual and controlled
manner.
10. The machine will shut off at the completion
of the cut. Turn off coolant flow and remove
workpiece.
11. Return bow to raised position for next cut.

20
11.4 Evaluating cutting efficiency
Is the blade cutting efficiently? The best way to
determine this is to observe the chips formed by
the cutting blade.
If chip formation is powdery, then the feed rate is
much too light, or the blade is dull.
If chips formed are curled, but colored — that is,
either blue or straw-colored from heat generated
during the cut — then the feed rate is too high.
If chips are slightly curled and are not colored by
heat – the blade is sufficiently sharp and is
cutting at its most efficient rate.
12.0 Maintenance
Before doing maintenance
on the machine, disconnect it from the
electrical supply by pulling out the plug or
switching off the main switch! Failure to
comply may cause serious injury.
Keep all surfaces clean and free of rust, slag,
chips, and coolant build-up.
Clear metal particles with a small paint brush or
parts cleaning brush.
Clean filter screen.
Do not use compressed air, as it may force
chips into the guide bearings and other critical
areas of the saw.
Wipe saw down with a clean, dry cloth, and oil
all unpainted surfaces with light machine oil.
Keep blade guides clean and free of metal
particles.
Check guide bearings frequently to make sure
that they are properly adjusted and turning
freely.
If the power cord is worn, cut, or damaged in
any way, have it replaced immediately.
Ball bearings on blade guide assemblies and
blade wheels are permanently lubricated and
sealed. They require no further lubrication.
Grease the vise lead screw (Figure 30) as
needed, with a general purpose grease.
Place a thin coat of oil on the table surface on
which the vise jaw slides.
Figure 30
12.1 Coolant level
Maintain coolant level. Low coolant level can
cause foaming and high blade temperatures.
Replace dirty coolant; dirty or weak coolant can
clog the pump, cause crooked cuts, a low cutting
rate and/or permanent blade damage. To fill the
tank, remove the filter cup and pour coolant into
the hole to about 80% of full capacity. Full
capacity is 9 liters (2.5 gal). Follow coolant
manufacturer’s instructions for proper use and
disposal.
12.2 Gear box
To change gear box oil:
1. Disconnect machine from power source.
2. Place bow in vertical position.
3. Remove drain plug (A, Figure 31) and drain
oil. (Follow local regulations for disposal of
used oil.)
Figure 31
4. Reinstall drain plug and return bow to
horizontal position.
5. Remove vent plug (B), and fill gear box
through the hole with approximately 0.3L
(10.14 oz.) of 90W oil.
6. Reinstall vent plug (B).
