f) Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
moving parts.
Loose clothes, jewellery or long hair can
be caught in moving parts.
g)
If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used.
Use of these devices can
reduce dust-related hazards.
4) Power tool use and care
a)
Do not force the power tool. Use the correct power
tool for your application.
The correct power tool will do
the job better and safer at the rate for which it was de-
signed.
b) Do not use the power tool if the switch does not turn it
on and off.
Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c)
Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools.
Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d)
Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition that may affect the power tools operation.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
g)
Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work to
be performed. Use of the power tool for operations differ-
ent from intended could result in a hazardous situation.
5) Service
a)

To ensure your safety and satisfaction, carefully read
through this OWNER’S MANUAL before using the product.
General Safety Rules
WARNING! Read all instructions Failure to follow all instructions
listed below may result in electric shock, re and/or serious injury.
The term “power tool” in all of the warnings listed below refers
to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
b) Do not operate power tools in explosive atmospheres,
such as in the presence of ammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodied plugs and
matching outlets will reduce risk of electric shock
b) Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) Do not abuse the cord. Never use the cord for carry-
ing, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
e) When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the inuence
of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal
injury.
b) Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your nger on the switch or plugging in power tools
that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.

TRACKING BLADE
Refer to Figures 9 and 12.
WARNING: Be very careful; Improperly tracked blade
may spring out from wheels causing serious injury. Do not
perform tracking adjustment while band saw is running.
●Disconnect band saw from power source.
●To check the blade tracking, rotate drive wheel by hand
in clockwise direction. View blade through tracking
window.
●Proper tracking is achieved when driver and idler wheels
are aligned. Tracking knob on the back of the tool frame
is used to tilt upper wheel and align blade wheels.
●If blade rides away from cabinet, turn knob clockwise. If
blade rides toward cabinet, turn knob counterclockwise.
●When blade is tracking properly, secure position by
tightening nut.
BLADE GUIDES
NOTE: Adjust blade guides only after blade has been
properly tensioned and tracked.
●Blade guides support blade at sides and rear of blade,
and prevent twisting or deection.
●Blade guides should not touch blade when no workpiece
is in contact with blade. Adjust guides as described in
following section.
UPPER BLADE GUIDES (Fig.10-11)
●Upper blade guides employ guide pins for side support
and a ball bearing for rear support.
●Loosen screws and adjust guide pins to sides of the
blade (see Figure 10). Use a feeler gauge to check that
guide pins are 0.002” away from blade.
●Lock adjustment by tightening screw.
●Adjust ball bearing at rear of blade by loosening socket
head bolt and repositioning shaft (see Figure 11).
●Position ball bearing 0.002” away from back of blade.
●Secure position of bearing by tightening socket head
bolt.
●Adjust the height of upper guide to clear the workpiece
by 1/4”. Loosen upper guide knob and adjust height of
upper guide until it clears workpiece by 1/4”. Tighten
upper guide knob.
LOWER BLADE GUIDES (Fig.12)
●Lower blade guides employ guide pins for side support
and bearing for rear support.
●Loosen screws (see Figure 12) and move guide pins
away from blade sides.
●Loosen socket head bolts and adjust lower guide bracket
position so that rear of blade is positioned 0.002” away
from bearing.
●Tighten socket head bolts.
●Adjust guide pins to sides of the blade. Use a feeler
gauge to check that guide pins are 0.002” away from
blade.
●Lock adjustment by tightening screws.
BLADE SELECTION
●Blade vary depending on type of material, size of
workpiece and type of cut that is being performed.
●Characteristics which make blades different are width,
thickness and pitch.
BLADE WIDTH
●Width of blade describes distance from tip of a tooth to
back of blade.
●Width of blade affects rigidity of blade. A wider blade
wanders less and produces a straighter cut.
●Width of blade also limits the smallest radius which can
be cut. A 1/4” wide blade can cut about a 1/2” radius.
BLADE THICKNESS
●Blade thickness describes the distance between sides
of blade. A thicker blade has more rigidity and stronger
teeth.
●A narrow thick blade is used to cut curves while a wide
thin blade is used to make long, straight cuts.
BLADE PITCH
●Pitch describes number of teeth per inch or tooth size. A
blade with more teeth per inch produces a smoother cut.
●The type of material being cut determines number of
teeth that should be in contact with the workpiece.
●For soft materials, the proper blade has between 6 to 8
teeth per inch.
●When cutting hard materials, where shocking is more
detrimental, use a blade with 8 to 12 teeth per inch.
●There should always be at least three teeth in contact
with cut to avoid shocking blade.
●Blade shocking occurs when pitch is too large and blade
tooth encounters too much material. This can strip teeth
from blade.
●Blade manufactures are prepared to supply information
about blades for specic applications.

- 8 -
TYPE OF CUT
●Contour cutting is done by guiding workpiece free-
handed to produce curved shapes.
●Bevelled cutting is done by tilting saw table and using
proper work guide method.
●Regardless of which work guiding method is used, a
workpiece which overhangs table by more than 5” needs
proper support.
CONTOUR SAWING
●When contour sawing, use both hands to keep workpiece
at against table and guided along desired path.
●Avoid positioning hands in line with blade. If hands slip,
they could contact blade.
●Try to stand to front of the saw and use hands over the
portion of table that is to right of blade and before cut.
●Cut small corners by sawing around them. Saw to
remove scrap until desired shape is obtained.
BEVEL CUTTING
●Perform bevel cutting by tilting table to desired degree.
●Unlock table by loosening locking handle located on the
backside of the unit.
●Tilt table to desired position by rotating knob.
●Lock table in position by tightening locking handle.
MITER GAUGE (Fig.13)
Use miter gauge for securing and holding workpiece at
desired angle to preduce angled cuts. Use scale to adjust
gauge to desired angle.
WARNING: Never use miter gauge and rip fence at the
same time. The blade might bind in the workpiece. Operator
could be injured and/or workpiece could be damaged.
PUSH STICK
When cutting the smaller workpieces, you can operate by
using the push stick for your safety.
BLADE CLEANING BRUSH
Make sure that brush is in contact with blade to properly
remove foreign particles from drive wheel.
MAINTENANCE
WARNING: Make certain that unit is disconnected from
power source before attempting to service or remove any
component.
CLEANING
●Keep machine and workshop clean. Do not allow
sawdust to accumulate on band saw.
●Keep wheels clean. Debris on wheels will cause poor
tracking and blade slippage.
●Keep mechanisms and threaded or sliding surfaces
clean and free of foreign particles.
●Operate band saw with a dust collector to minimize clean
up.
LUBRICATION
●The shielded ball bearings are permanently lubricated
and require no further lubrication.
●Small amounts of machine oil can be applied to belt
tension mechanisms and threaded or sliding surfaces.
●Occasionally apply a coat of paste wax to tabletop to
keep it slick and corrosion free.
KEEP BAND SAW IN REPAIR
●If power cord is worn of cut in any way, have it replaced.
●Replace any damaged or missing part.
●Use parts list to order parts.
