ANNUAL SERVICE CHECKS
Perform the following service checks at least once
each year:
Replace Hydraulic Oil and Oil Filter.
Drain hydraulic reservoir, clean and replace oil.
Wipe away dirt and excess oil from around filter using
cleaning cloths and alcohol solvent.
Loosen and remove filter. Use absorbent cloths to
keep excess oil from leaking onto the machine.
Discard used filter.
Wipe away dirt and excess oil from around filter
housing.
Install new filter. Do not over-tighten.
With the fill port cap on but not tightened, completely
raise and lower all booms to bleed trapped air from
the lift cylinders. Repeat as necessary.
Replace yearly, or whenever filter or oil contamination
has a noticeable effect on boom functions.
Inspect pivot pins and cylinders, including rod
ends, for wear or damage. Replace as necessary.
Visually inspect welds and structural
components for wear, damage and corrosion.
Follow all manufacturer’s recommendations when
making repairs to critical components.
Personnel making repairs to welds should be certified
in accordance with applicable government
regulations.
Inspect outriggers for wear or damage. Repair or
replace as necessary.
Verify that Level Sensor is operating correctly.
Fully deploy outriggers until all Outrigger LEDs and
AUTO LEVEL LED are lit, and buzzer sounds.
Verify that machine is level, and that level sensor is
giving an accurate reading.
Repair or replace as necessary.
Inspect and adjust axles and brakes.
Load test boom lift operations with 500 lb (187
kg) load.
Check slew bearing for wear or damage.
Check bolts for wear or damage.
With the boom lift fully retracted, measure the
distance between the slew ring gear and the
horizontal plate above. Use a 2-inch (50 mm) caliper
or bore micrometer. Record the measurement (Figure
3-4).
Place a 175 lb (65 kg) load on the boom lift platform.
Measure the distance between the slew ring and the
horizontal plate above. Record the measurement.
If the difference in measurements is greater than .25
in (6.35 mm) the slew ring bearing should be
replaced. Contact manufacturer for replacement
instructions and assistance.
