3. Clean the area around the hydraulic oil filter and
remove the filter (Fig. 48).
4. Remove the tube that connects the axle housing to the
transmission and allow the oil to flow into a drain pan.
5. Install new hydraulic oil filter and connect the tube
between axle housing and transmission. Fill axle
(reservoir) to proper level (approx. 5 qt); refer to Check
Hydraulic System Fluid. Remove jack stands.
6. Start engine, cycle steering and lift cylinders, and check

Adjusting 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 do not work effectively. Free travel is the distance
the brake pedal moves before braking resistance is felt.
The brakes should be checked for adjustment after the first
25 hours of operation and should only need adjusting after
considerable use thereafter. These periodic adjustments can
be performed where the brake cable connect 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 lock arm from right brake pedal so both
pedals work independently of each other.

2. To reduce free travel of brake pedals — tighten the
brakes — loosen front nut on threaded end of brake
cable (Fig. 49). Then tighten rear nut to move cable
backward until brake pedals have 1/2 to 1 inch (13 mm
to 25 mm) of free travel. Tighten front nut after brakes
are adjusted correctly.

Changing Rear Axle Lubricant

After every 400 hours of operation the oil in the rear axle
must be changed.
1. Position machine on a level surface.
2. Clean area around the (3) drain plugs, (1) on each end
and (1) in the center (Fig. 50).
3. Remove plugs allowing oil to drain into drain pans.
4. After oil is drained, apply thread locking compound on
drain plug threads and reinstall in axle.
5. Fill axle with lubricant; refer to Check Rear Axle
Lubricant.
