MAINTENANCE
CHECKLIST C
PROCEDURES
C-1 Replace Hydraulic Oil Tank Air
Filter
Replacing the air filter of the hydraulic oil tank is
important for the proper operation and the service life of
the machine. A dirty or blocked filter may cause the
machine to operate improperly. The hydraulic
components may become damaged if a dirty or blocked
filter remains in use. Replace the filter more frequently
in very dirty environments.
NOTICE
This procedure must be performed when the drive
motor/hydraulic motor is stopped.
BURN HAZARD
Allow the hydraulic oil to cool to
room temperature before servicing
the hydraulic system.
HIGH-PRESSURE HAZARD
Slowly remove the hydraulic
components to reduce hydraulic
oil pressure. High hydraulic oil
pressure could penetrate the skin.
Seek medical attention
immediately.
1. Remove the air filter from the hydraulic tank.
2. Install and tighten the new air filter.
3. Clean all oil spills during the replacement process.
4. Start the machine and inspect the filter and
hydraulic components to ensure no leakage exists.
CHECKLIST D
PROCEDURES
D-1 Inspect Scissor Arm Installation
Bearing
Effectively maintaining the scissor arm installation
bearing is important for proper operation of the
machine. Repeated use of an old bearing may damage
parts and cause unsafe operation.
NOTICE
Perform this procedure when the scissor arm has
been fully retracted.
1. Measure the clearance between the shaft and the
shaft sleeve with a feeler gauge.
2. Replace the shaft sleeve when the clearance is
greater than 0.3 mm (0.011 in) or the service life is
10 years.
D-2 Inspect Chassis Slider
Properly maintaining the slider is important for safe op-
eration of the machine. The chassis slider slides on the
channel steel surface to form a friction pair. Use of an
improper slider or repeated use of an old slider could
damage parts and cause unsafe operation.
NOTICE
Perform this procedure when the scissor arm is in
the fully retracted state.
1. Measure the distance from the bottom surface of
every slider at the sliding end to the center of the in-
stallation shaft. (Reference size: 68 mm[2.67 in.]).
2. Result: Replace the slider when it shows wear
measuring more than 3 mm (0.11 in.) (the measured
distance L is less than 65 mm[2.55 in.]). See
