Maintenance Information

Return filter

Return filter. On MHP13/35 models, the hydraulic oil
return filter is mounted in hydraulic oil reservoir.
The filter element is a throw-away type filter and
should be changed after the initial break-in period
(approximately 50 hours operation time).
The filter is equipped with an (optional) hydraulic
pressure gauge to indicate the filter element
condition. A by-pass relief within the filter base is
provided and is set to by-pass at 25 PSI. If pressure
readings are above 25 PSI, the filter should be
changed.
The filter condition should be checked at the 90 day
or 150 hour Preventive Inspection Maintenance
interval or more frequently under extreme working
conditions.
The filter condition indicator is accurate only when
the engine is running at maximum RPM and pump is
discharging maximum flow, which occurs only
during full speed. This requires that the indicator be
observed while the unit is in motion. Oil temperature
should be at least 70 degrees.
CAUTION
Use extreme caution while observing the
condition indicator because of the motion of
the boom. The condition indicator is best
observed from outside of the tract of the
vehicle wheels to avoid a possible unsafe
condition.
When changing the filter element, the oil inside of
the filter element, should be examined for deposits
of metal cuttings, which if present, could indicate
excessive wear in some of the system components.

Battery

Battery. The battery will have longer life if the water
level is maintained and it is kept charged. The unit
will have better starting characteristics with a fully
charged battery.
In cold weather the battery should be maintained at
full charge to keep from freezing. An extremely low
or dead battery can freeze in cold weather. Make
sure connections are clean and tight.
Make sure charging equipment is operating
properly.
