OPERATING INSTRUCTIONS
Read and understand the safety rules and assembly
instructions.
2. For best snow removal results, the tractor should be placed
in
first gear with the engine RPM at 3/4 to full speed.
3.
Determine the best snow removal pattern. Consider the
size, shape, and terrain to be cleared and the obstructions in
the area.
4. Drive
forward and back. The long direction is usually the
best to minimize turning.
5. Whenever possible, begin snow removal on the upwind
side of the driveway or sidewalk so it is not necessary to
blow snow over an already cleared area.
6. The Deflector should be rotated to discharge the snow
downwind, not into it. Always adjust the Deflector so that
you are well out of the path of the snow stream.
7. Deposit the snow beyond the area to be cleared if possible.
8. For
light to medium snow depths, the snow blower may be
used
with minimum auger overlap from your previous path.
With deep and very heavy snow conditions, the amount of
overlap should be increased so not to force more snow into
the unit than it will easily handle without clogging.
9.
Should the snow blower become clogged, disengage the
PTO, turn off the engine and remove the key. Get off the
tractor and dislodge the clog. Return to the tractor and
proceed to clear the snow.
10. The
snow blower should be transported in araised position
with the PTO disengaged.
By
following these instructions, you should have asafe and
effective piece of equipment.

ASSEMBLY INSTRUCTIONS
PURPOSE:
This Snowblower is manufactured by Engineering Products
Co., Inc.
and the Haban Manufacturing Co., for use on Power
King Tractors. It is intended for use in the removal of snow from
sidewalks, driveways, and other moderately large areas in a
safe and
effective manner. Strict adherence to the assembly,
safety,
and operating instructions will ensure that the unit will
have along and safe life.
ASSEMBLY:
The Auger Assembly and Chute Deflector are contained in
one carton, while the Hitch and Lift Link Assemblies are in
another.
Be sure you have both cartons.
1. Remove the AUGER ASSEMBLY, Chute DEFLECTOR (Item
60),
and Chute Direction Control ROD (Items 79,80,81 and
82)
from the first carton. To attach the Deflector to the
Auger Assembly, loosen the four (4) SCREWS (Item 76) at
the base of the Deflector, apply a small amount of grease to
the inside of the Deflector Base, and place it on the Auger
Assembly. Tighten the four Screws previously loosened.
2.
Attach the ends of the Deflector Control CABLE (Item B) to
the opposite side (left with Snowblower facing forward) of
the Deflector by removing Cable BOLT (Item 63) and
WASHER (Item 62). Place both cable loops over the weld
nut and replace the bolt and washer.
3. Loosen the six Item "C" SCREWS on the bottom and sides
of
the Auger Assembly Channel. Also loosen two Item "B"
SCREWS on either side of the Channel. From a position
behind the Auger Assembly, slide the Hitch Assembly into
the Channel, making sure the EYEBOLTS (Item 57) with one
NUT (Item 59) on
the Channel Side of each, are in the holes
in
the Hitch Adjusting Blocks on the Hitch Frame. Place
second NUT (Item 59) on Eyebolt
outside of Hitch
Adjustment Blocks.
NOTE: Due to
manufacturmg variation on the widlh
of the Auger Assembly Channel, it may be necessary
on some
units to adjust the distancebelweenthe two
Hitch bars that enter the Auger Assembly Channel In
order to get a sliding fit. This can be accomplished by
carefully bending the bars. This will not affect the
performance of the unit. Patience and care in this
matter will make later belt adjustment much easier.
4. Remove the Channel COVER (Item 83). Place the shorter,
driven BELT (Item 130) around the Auger Assembly
SHEAVE (Item 47) and the lower groove of the three-groove
SHEAVE (Item 102) at the rear of the Hitch Assembly (see
Figure
4). By loosening and/or tightening the Nuts on the
Eyebolts, position the Hitch Assembly so that Belt tension is
properly adjusted. Pull up on the spring loaded Idler Arm
and place the belt under the Idler PULLEY (Item 125). Tool
tighten the Screws on sides and bottom of Auger Assembly
Channel, and the Nuts on the Eyebolts.
5. With the Hitchl Auger Assembly in a position under the
tractor, Idtthe rear of the Hitch into the Rear Hitch Blocks on
the frame of the tractor. Raise the front of the assembly so
that the front crossbar fits into the Front Hitch Blocks on the
frame of the tractor. Secure with Safety LATCHES {Item
114) by
Inserting aBlank BOLT(ltem 116)throughthe latch
and sma
II upper hole in Front Hitch Block and retaining with
a Quick Change KEY (Item 113).
6. Relieve tension on driven BELT (Item 130) by removing it
from under Idler PULLEY {Item 125). Allow it to temporarily
drop off of lower groove of the three-groove SHEAVE (Item
1021.
Disconnect the safety chain and electrical wire
harness from the Electromagnetic Clutch at the front of the
tractor engine. Loop the longer, Drive BELT (Item 129) over
the rearmost belt groove of the Electromagnetic CIU1Ch
Pulley (except the 16 hp model where the front belt groove
should be used). Thread the Drive Belt under the right Idler
PULLEY (Item
119) and around the top of the three-groove
SHEAVE. Lift up on the spring loaded lefl Idler Arm and
place
the belt under the left Idler PULLEY (Item 119) and
release arm.
This will a utomatically apply proper tensIOn to
Drive Belt. Replace
driven Belt in lower groove of three-
groove Sheave as provided in paragraph 4.
7. For
Model 1612 and all other tractors with serial numbers
before 52589, place the tractor lift in such a position that
the bottom of lift arm is as far forward as possible. Attach
the Lift Link to the Lift Arm on the right side of the Hilch
Assembly using the Blank BOLT (Item 135), 1" SPRING
(Item 136), WASHER (Item lOB) and a
Quick Change KEY
(Item 145). Referring to
the Universal Lift Link diagram
(Figure 6). use positions Cand E for model 1612, and
positions Cand 0for other tractors.
8. For
tractors other than the Model 1612 and with serial
numbers after 52589, attach the Lifl Li nkROD (Item 139) to
the Lift Arm with aSCREW (Item 138) and NUT (Item 110).
Connect the
other end of the Rod to the hole avai'lable in the
Rear
Lift Link Rod just in front of where it is attached to the
Lift Assembly Arm (as shown In Tractor Owner's Manual).
using the SCREW (Item 140) and aNUT (Item 110).
9.
Mount the Chute Control Rod BRACKET (Item 132) to the
right side of the flywheel housing using two SCREWS (Item
131). two lock WASHERS (Item 142) and two flat
WASHERS (Item 143). Insert upper section of ROD (Item 79)
through the Bracket. Attach the lower section of the ROD
(Item 82) to EYEBOLT (Item 9) on
the Auger Assembly and
slide
the two sections of the Rod together. Install Quick
Change KEY (Item 81) in hole in upper section below
Bracket.
10.
Adjust the height of the Skid SHOES (Item 2) by loosening
the two Screws holding the Shoes tothe Auger Assembly. If
the
Snowblower IS to be used on a smoolh surface, such as
concrete
or asphalt, the Shoes should be adjusted so that
lhe Scraper Blade is resting flat on the surface. If the
intended use is on agravel or loose material surface, the
Shoes should be adjusted to allow for a 1" clearance
between the Blade and the surface. To do this, lift the
Snowblower and place a 1" thick board under the Scraper
Blade. Lower the Snowblower and adjuslthe Skid Shoes so
that they are resting on the surface.
11. Check
the adjustment of the Auger Drive CHAIN (Item 34). If
correct, the chain will have a slight amount of slack In It. In
the event the Chain is not properly adjusted, loosen the
NUTS (Item 50) on
the back of the Auger Assembly. By
moving these Nuts In orout you will be moving the jackshaft
and adjustIng the Drive Chain. When the Chain is properly
adjusted, tighten the Nuts loosened previously.
NOTE.
If there was an excessive amount of
adj ustment reqUired, go back to step 4and readjust
the belt tension.

MAINTENANCE INSTRUCTIONS
1. The snow blower has a grease fitting located on the Auger
Jackshaft (Item 40, Figure 1) which should be greased every
10 hours or use with a multi-purpose grease.
2. Once a
year or more often depending on usage, the chain
tension should be checked and adjusted if required and
lubricated.
3. Drive belt tension should be checked periodically and
adjusted when needed. The belts should be checked for
wear also at this time. Replace worn and frayed belts.
4.
To store the snow blower for the off-season, remove the
snow blower from the tractor. Use water and a brush to
thoroughly clean the Auger Assembly and Hitch. Paint any
chips or worn areas, and put a light coat of oil on the unit to
prevent rust. Lubricate all moving parts, bearings, sheaves,
cross shafts. etc. Cover with atarp or plastic and store in a
dry place.
