Check The Hydraulic Filter Condition Indicators - Genie S-105 Service Manual

Section 3 • Scheduled Maintenance Procedures
CHECKLIST A PROCEDURES
A-6
Check the Hydraulic Filter
Condition Indicators
Genie requires that this procedure be performed
daily.
Note: Perform this procedure after the machine
reaches operating temperature. The amount of time
this takes will vary, depending on ambient air
temperature.
Maintaining the hydraulic filters in good condition is
essential to good system performance and safe
machine operation. The filter condition indicators
will show when the hydraulic flow is bypassing a
clogged filter. If the filters are not frequently
checked and replaced, impurities will remain in the
hydraulic system and cause component damage.
Note: There are four hydraulic filters on the
machine: one tank return filter, one medium
pressure filter and two high pressure filters. All the
filters have condition indicators on them, except the
medium pressure filter.
1 Start the engine from the ground controls.
2 Press and release the engine idle select button
to change the engine rpm to high idle.
3 - 10
Tank return filter
Note: The tank return filter indicator needle may
operate in the red area when hydraulic oil is below
50° F / 10° C.
Note: If the return filter indicator needle is not
operating in the green area after performing
previous daily procedures, continue running engine
until hydraulic oil temperature is at least
50° F / 10° C.
3 Open the ground control side turntable cover and
inspect the filter condition indicator gauge.
Result: The needle on the gauge should be
operating in the green area. If the needle is in
the red area, this indicates that the hydraulic
filter is being bypassed and the filter needs to
be replaced. See D-11, Replace the Hydraulic
Filter Elements.
