A-13
Perform Generator Maintenance-
Marathon Models
Generator specifi cations require that this
procedure be performed every 200 hours or
quarterly, whichever comes fi rst.
Maintaining the generator in good condition is
essential to safe machine operation and long
service life. Storing the generator in a harsh
environment may require this procedure be
performed more frequently. Allowing dirt and
grease to build up on the generator may result in a
generator which will run hotter, lose effi ciency, and
reduce the life of the generator.
1 Remove all dust, dirt, and oil and grease build-
up from the external surfaces of the generator.
2 Use low-pressure compressed air
(25 psi / 1.7 bar) to blow dirt and grease from
the internal components through the fan
opening.
3 Locate the Capacitor Box at the top of the
generator. Remove the cover, clean the inside
of the box and check for loose or damaged lead
wires and components mounted in the box.
4 Replace the cover. Securely tighten the
fasteners. Do not over tighten.
CHECKLIST A PROCEDURES
A-14
Adjust the Brakes (if equipped)
Axle specifi cations require that this procedure be
performed initially at 250 miles of use.
Maintaining the axle brakes in good condition is
essential to safe operation and good performance.
Brakes which are out of adjustment can result in
longer stopping distances and excessive brake
wear on the towing vehicle. Component damage
may also result if problems are not discovered and
repaired in a timely fashion.
Note: Perform this procedure with the machine
on a fi rm, level surface with the machine in the
stowed position.
1 Select a wheel. Chock the front and rear of the
tire at the opposite side of the machine.
2 Place a lifting jack under the axle near the
brake to be adjusted. Lift the axle until the
wheel is off the ground and place a jack stand
under the axle. Lower the axle onto the jack
stand.
3 Working from the back side of the wheel at the
brake backing plate, locate and remove the
small rubber plug from the lower side of the
backing plate to access the star-shaped brake
adjuster wheel. Set the plug to the side.
4 Insert a brake adjuster tool into the opening of
the brake backing plate, engaging it with the
teeth of the brake adjuster wheel. Move the tip
of the adjuster tool in an upwards direction to
tighten the brakes.
Note: It may be helpful to use a fl ashlight when
locating the brake adjuster wheel.
