FINAL ADJUSTMENTS
1. Complete installation of lift chain by inserting the
loose end of lift chain through stop link on the lift
arm. Fasten to holes in the A-frame using a 3/8"
U-bolt, lock washer, and nut with the last link of the
chain. Adjust the lift chain to allow 6" extension of
lift rod and 2-3" slack in chain in the float mode.
Tighten.
2. Complete electrical installation in vehicle and install
control. Attach plow to vehicle.
3. Fill the hydraulic unit to top of fill hole with hydraulic
fluid.
System Capacity:
Reservoir – 1-3/4 quart
Complete System – 2-3/8 to 2-3/4 quarts
4. Raise and lower the snowplow several times. Be
sure to completely retract the lift ram each time.
Return to the lower position, retracting the lift ram
completely.
5. With the blade lowered, add more hydraulic fluid to
the reservoir. Keeping the blade to the ground,
angle the blade several times in each direction.
6. With the lift ram fully retracted, add enough
additional hydraulic fluid to bring fluid level to top of
fill hole.
7. With plow attached to properly ballasted vehicle
and blade lowered to ground, the A-frame should
be parallel with the ground. If not, reposition
A-frame using upper or lower pushear holes.
8. For reliable operation and to prevent damage to
the 6-1/2" lift arm retraction spring, the length of
the cable must be adjusted when attached to the
vehicle it will be used on. With the lift ram fully
collapsed, wrap the cable tightly around the
thimble, shorten/lengthen the cable to remove all
slack from the cable, then tighten the cable
clamps.
9. After adjustment, excess cable should be trimmed
off close to the second cable clamp. Cover cut end
of cable with electrical tape. Excessive spring
tension will make attaching/detaching difficult and
overextend the spring.
WARNING
Keep 8' clear of the blade when it is being
raised, lowered or angled. Do not stand
between the vehicle and blade or directly in
front of the blade. If the blade hits or drops on
you, you could be seriously injured.
CAUTION
Do not mix different types of hydraulic fluid.
Some fluids are not compatible and may cause
performance problems and product damage.
