Seat Belt - Replace
Within three years of the date of installation or within
five years of the date of manufacture, replace the seat
belt. Replace the seat belt at the date which occurs
first. A date label for determining the age of the seat
belt is attached to the seat belt, the seat belt buckle, and
the seat belt retractor.

Consult your Caterpillar dealer for the replacement of
the seat belt and the mounting hardware.
If your machine is equipped with a seat belt
extension, also perform this replacement procedure for
the seat belt extension.
Stabilizer and Cylinder
Bearings - Lubricate
Illustration 284 g01013784
If your machine is equipped with stabilizers, lubricate
the stabilizer cylinder bearings and the legs of the
stabilizer through eight fittings.
Tire Inflation - Check
Personal injury can result from improper tire inflation.
A tire blowout or rim failure can result from improper
or misused equipment.
Use a self-inflating chuck and stand behind the tread
when inflating a tire.
Proper inflating equipment, and training in using the
equipment, are necessary to avoid overinflating.
Before inflating tire, put the tire in a restraining device.
Some machines are equipped with tires that are filled
with air. Other machines are equipped with tires that are
filled with foam. Pressures of tires that are filled with air
must be checked. Pressures of tires that are filled with
foam do not require checking.
1. Park the machine on level ground. Apply the
parking brake. Retract and lower the boom. Shut off
the engine.
2. Clean the area around the valve stem.
3. Remove the dust cover for the valve stem.
4. Stand behind the tire tread and use a Caterpillar
4S-6524 Pressure Gauge, or 1P-0545 Pressure
Gauge to check the tire pressure. If these pressure
gauges are not available use an equivalent tool to
check the tire pressure. Add air if the pressure is
low.
5. Install the dust cover on the valve stem.
Refer to the following additional information about tire
inflation:
• Operation and Maintenance Manual, "Tire Shipping
Pressure"
• Operation and Maintenance Manual, "Tire Inflation
Pressure Adjustment"
Consult your Caterpillar Dealer for further information on
the correct operating pressures and the correct load
ratings.
