NOTE:
Use only special Grade 8 for replacement of the
mast bolts. Order the bolts from your dealer, see
your parts manual.
If a broken bolt is found, replace the bolt and also
replace the bolt on each side of the broken bolt.
The proper bolt torque will not be obtained without
the hardened steel washers under the bolt heads
on the outer (mast) bolt circle.
Front Axle Mounting Bolts
Torque the 1” axle mounting bolts (8) to 575 lb-ft. (782 Nm).
See Figure 6-29.
500 Hours of Operation (3 Months)
NOTE:
You must read and understand the warnings and
basic safety rules, found in Section 2 of this
manual, before performing any operation or
maintenance procedures.
For additional engine maintenance guidelines, see
the engine manual furnished with this crane.
Inspect the Tires
Inspect the tires for any signs of damage, such as cracks,
large gouges, deterioration, etc. If damage is found, it must
be carefully analyzed to determine if the tire is safe to use.
Replace all tires that are unsafe.
Inspect Parking Brake Pads
NOTE:
It is necessary to climb under the crane to check
the parking brake pads. Be sure engine is shut off,
the ignition key is removed and chock blocks are in
place before climbing under the crane.
Inspect the thickness of the brake pads (Figure 6-30).
Replace the brake pads if they are 0.028 inches (0.71 mm)
thick or less.
Check the surface condition of the brake disc. Replace the
disc if badly warped, pitted or out of tolerance.
Replace Fuel Filter (Diesel Engine)
See the engine operator’s manual furnished with the crane
and follow the replacement procedures.
NOTE:
If the filter is not filled with fuel prior to installation,
the engine will not start due to air in the fuel
system. The fuel system will have to be bled as

Replace Air Cleaner Element
NOTE:
Service the air cleaner only with the engine shut
down. Dirt and debris can enter the engine and
cause damage if the engine is operated with the air
cleaner element removed.
1.
Remove the housing cover.
2.
Remove the wing nut securing the air cleaner element to
the air housing. Remove the element as gently as
possible until you get it outside of housing. Accidently
bumping it while it is still inside the housing means
dropped dirt and dust that may contaminate the clean
side of the air cleaner housing, before the new element
has a chance to do its job.
3.
Remove the safety filter.
4.
Clean the inside of the housing carefully. Any dirt left
inside the housing could cause damage to the engine.
Use a clean, water-dampened cloth to wipe every
surface clean. Check it visually to make sure it is clean
before installing a new element.
5.
Always clean the gasket sealing surfaces of the housing.
An improper gasket seal is one of the most common
