CHECK INSTRUMENTS OPERATION
Allow the engine to warm up for about five minutes
before beginning operation. Indicator lamps should be
OFF and gauges should register normal readings. Tilt
the frame from side to side with the level control and
note the angle indicator movement.
CHECK GENERAL MACHINE
OPERATION & CONDITION
Are any decals missing or damaged? Are all guards,
shields and covers in place? Do all controls function
smoothly and properly? Are there any abnormal vibra-
tions or noises? Are any hose or fitting connections
leaking? Is the engine exhaust color normal (light grey
or colorless)?
LUBRICATE GREASE POINTS
Refer to the Lubrication chapter of this manual for
weekly grease fitting locations and other related
details.
The following initial oil and filter changes should be
made at this time on a new machine. Thereafter these
changes should be made at the regular maintenance
schedule listed. Refer to those schedules for proce-
dures necessary.
Engine Oil & Filter
(250 Hours)
Transmission Oil & Filter
(1000 Hours)
Hydraulic Oil Filter

NOTE:
Perform all other service requirements
up to this point as well as the following:
CHANGE AIR FILTER ELEMENT
This air filter contains a single dry element. Wipe the
outside of the body with a rag or cloth. Blow off excess
dirt and dust with compressed air. Refer to illustration
on the next page.
When removing tires follow industry safety practices.
Deflate completely prior to removal. Following assem-
bly of the tire on the rim, use a safety cage or restrain-
ing device while inflating.
CHECK WHEEL NUT TORQUE
On NEW machines, re-torque until 450 ft-lbs (610
Nm) is maintained.
Service Every 50 Hours or Weekly
Service Every 250 Hours
100 Hours (New Machine Only)
WARNING
NEVER attempt to service tires if the bead lock
ring appears loose. Clear the area and call for
professional tire repair help.
Inflating or servicing tires can be dangerous.
Whenever possible, trained personnel should
service and mount tires. DO NOT place your
fingers on the tire bead or rim during inflation;
serious injury or amputation could result. To
avoid possible death or serious injury, follow
the safety precautions below:
1. BE SURE the rim is clean and free of rust.
2. Lubricate both the tire beads and rim
flanges with a soap solution. DO NOT use oil
or grease.
3. Use a clip-on tire chuck with a remote hose
and gauge which allows you to stand clear of
the tire while inflating it.
4. NEVER inflate beyond 35 PSI (240 kPa) to
seat the beads. If the beads have not seated
by the time the pressure reaches 35 PSI (240
kPa), deflate the assembly, reposition the tire
on the rim, relubricate both parts and re-
inflate. Inflation pressure beyond 35 PSI (240
kPa) with unseated beads may break the bead
or rim with explosive force sufficient to cause
death or serious injury.
5. After seating the beads, adjust the inflation
pressure to the recommended operating pres-
sure listed.
6. DO NOT weld, braze, or otherwise attempt
to repair and use a damaged rim.
