Q-10
Inspect the Hydraulic Filters
Genie specifications require that this procedure be
performed quarterly.
Maintaining the hydraulic filter in good condition is
essential to good system performance and safe
machine operation. The filter condition indicator will
show when the hydraulic flow is bypassing a
clogged filter. If the filter is not frequently checked
and replaced, impurities will remain in the hydraulic
system and cause component damage.
Note: There are four types of hydraulic filters: tank
return filter, medium pressure filter, high pressure
filter and drive motor case drain filter. The quantity
and type of filter(s) may vary by model.
Models with Filter Condition Indicator:
1 Start the engine from the ground controls.
2 Set the engine idle to high rpm (rabbit symbol).
3 Visually inspect the filter condition indicator.
Result: The filter condition indicator is
operating in the green area.
Result: The filter condition indicator is
operating in the red area. This indicates that
the hydraulic filter is being bypassed and the
filter should be replaced. Refer to
Maintenance Procedure,
Replace the
Hydraulic Filters.
Models without Filter Condition Indicator:
Note: Models without a filter condition indicator
cannot be inspected. At the required maintenance
interval, replace the filters.
Hydraulic Tank Cap (if equipped):
1 Remove the breather cap from the hydraulic
tank.
2 Check for proper venting.
Result: Air passes through the breather cap.
Proceed to step 4.
Result: If air does not pass through the cap,
clean or replace the cap. Proceed to step 3.
Note: When checking for positive tank cap venting,
air should pass freely through the cap.
3 Using a mild solvent, carefully wash the cap
venting system. Dry using low pressure
compressed air. Repeat this procedure
beginning with step 2.
4 Install the breather cap onto the hydraulic
tank.
