MAINTENANCE
• Add fresh hydraulic oil until level is visible
in the sight gauge. A 1/4 – 1/2 air bubble
will be seen at the top of the gauge.
• Install and tighten return filter cap.
• Idle engine 2-3 minutes, stop engine and
check for proper hydraulic oil level and
leaks.
CAUTION: If hoses, filter and/or hydraulic compo-
nents were changed, start the engine and purge the
air from the system prior to checking the oil level.
To do this, idle the engine for three minutes with
control lever in neutral position. Slowly engage
forward to reverse. This allows fluid to replace air
introduced with the filter change. If this procedure
is not followed, partial or complete failure of the
pump may result.
NOTE: When changing the hydraulic oil, it is
recommended to also change the hydraulic oil filter.
HYDRAULIC OIL FILTER
Replace every 100 hours. Never let the filter be
completely clogged. Use Stauff Filter P/N 45150.
CAUTION: Never overfill the hydraulic tank. Use
the sight gage located on the hydraulic tank. A 1/4-
1/2” air bubble will be seen at the top of the gauge
showing the fluid level. Before disconnecting any
hydraulic lines, be sure engine is shut off and relieve
all pressure. Before applying pressure to system, be
sure all connections are tight and lines, fittings and
hoses are not damaged.
HYDRAULIC BREATHER CAP
Replace every 800 hours or yearly. Use Stauff
breather P/N 38521. To replace breather, use a hex
wrench directly under cap.
