CHECK CLUTCH OPERATION
Brush must stop quickly when attachment
clutch lever is released.
Wheels must stop quickly when traction drive
clutch lever is released.
If clutches do not engage or disengage
properly, adjust or repair before operation.
See Attachment Clutch/Brake Adjustment on
page 24 and Traction Drive Clutch
Adjustment on page 26.
CHECK CLUTCH SPRING
ADJUSTMENT
Make sure the attachment clutch and traction
drive clutch are adjusted to the range
specified in Attachment Clutch/Brake
Adjustment on page 24 and in Traction Drive
Clutch Adjustment on page 26.
CLEAN ENGINE
Refer to Engine Manual for detailed
instructions.
CLEAN RECOIL
GUARD FOAM COVER
Make sure the recoil guard foam cover is
always kept clean and free of snow and
debris.
If cover becomes clogged with debris gently
vacuum the foam or wash with warm water.
NOTE: Cover is not necessary for operation
during the non-winter months.
If cover is clogged with snow remove it
immediately and allow foam to thaw or rinse
with warm water.
IMPORTANT: Allow foam to dry completely
before reinstallation.
See Recoil Guard Foam Cover Installation on
page 21.
CHECK ENGINE OIL
The engine crankcase oil should be checked
every 5 hours of operation. Oil level MUST be
maintained in safe operating range on
dipstick at all times or engine damage will
result (see Engine Manual).
Park unit on a level surface. Refer to Engine
Manual for detailed instructions.
CHANGE ENGINE OIL
Change oil after first 2 hours of operation,
thereafter change oil every 25 hours (more
often if required). Refer to Engine Manual for
detailed instructions.
Run engine just prior to changing oil. Warm
oil will flow more freely and carry away more
contamination.
CHECK TIRE PRESSURE
Keep tires at pressure listed on the tire
sidewall.
GENERAL LUBRICATION
Brush Drive Chains & U-joints
1. Chains and u-joint friction areas should
be oiled after first 5 hours of operation
and every 25 hours thereafter.
2. To access drive chains remove the two
bolts attaching the front and rear end
covers on each side of the brush guard
(Figure 11).
CAUTION: Avoid injury! Explosive
separation of tire and rim parts is
possible when they are serviced
incorrectly:
• Do not attempt to mount a tire
without the proper equipment
and experience to perform the
job.
• Do not inflate the tires above
the recommended pressure.
• Do not weld or heat a wheel and
tire assembly. Heat can cause
an increase in air pressure
resulting in an explosion.
Welding can structurally
weaken or deform the wheel.
• Do not stand in front or over the
tire assembly when inflating.
Use a clip-on chuck and
extension hose long enough to
allow you to stand to one side.
