After two minutes, check the transmission fluid
level; refer to Check Hydraulic System Fluid,

Adjusting the Service Brakes
Adjust the service brakes when there is more than one
inch (25 mm) of "free travel" of the brake pedals, or
when the brakes don't work effectively. Free travel is
the distance the brake pedal moves before you feel
braking resistance.
Check brake adjustment after the first 25 hours of
operation. After that, they should only need adjusting
after considerable use. These periodic adjustments can
be performed where the brake cable connects to the
bottom of the brake pedals. When the cable is no
longer adjustable, the star nut on inside of the brake
drum must be adjusted to move the brake shoes
outward. However, the brake cables must be adjusted
again to compensate for this adjustment.
1.
Disengage the lock arm from the right brake
pedal so both pedals work independently.
2.
To reduce free travel of the brake pedals, loosen
the front nut on the threaded end of the brake
cable (Fig. 37). Then tighten the rear nut to move
the cable backward, until the brake pedals have
13 mm to 25 mm of free travel. Tighten the front
nut after the brakes are correctly adjusted.

Changing Rear Axle Lubricant
After every 400 hours of operation, the oil in the rear
axle must be changed.
1.
Position the machine on a level surface.
2.
Clean the area around the three drain plugs, (1)
on each end and (1) in the center (Fig. 38).
3.
Remove the plugs, allowing the oil to drain into
drain pans.
4.
After oil is drained, apply thread-locking
compound on the drain plug threads and install it
in the axle.
5.
Fill the axle with lubricant: refer to Checking the
Rear Axle Lubricant, page 17.
