Note
If it becomes necessary to add or use an oil other
than the recommended fluid, it is important that it be
compatible and equivalent to the factory fill. Local oil
suppliers can generally furnish this information.
If questions still remain, contact Snorkel Customer
Service Department for further information.
Engine
Engine – Item 7. Refer to the engine manufacturer's
instruction manual or consult your local engine service
representative if engine adjustments or repairs are
needed. The engine must be operated in accordance
with manufacturer's instructions and serviced at rec-
ommended intervals.
Door Hinges and Latches
Door hinges and latches – Item 8. After lubricating,
remove any excess lubricant or over spray so it will
not collect dirt or debris.
Platform Rotator
Platform Rotator – Item 9. Platform rotators will require
lubrication only if disassembled for repairs. Consult
factory for proper lubricant if replacement of platform
rotator is required.
Hydraulic Oil Return Filter
Return filter – Item 10. The hydraulic oil return filter
is located next to the side of the proportioinal control
valve.
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 a 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 driving. This requires that the indicator
be observed while the unit is in motion, booms fully
retracted and in stowed position, drive range switch
in "LO" position, and drive controller fully forward. Oil
temperature should be at least 70° F (21° C).
Warning
Use extreme caution while observing the condi-
tion indicator because of the motion of the drive
wheels. The condition indicator is best observed
from outside of the tract of the vehicle wheels
Maintenance – 12
to avoid possible personal injury or machine
damage.
The return filter hose is equipped with a check valve
to limit leakage from the reservior while the element
is being changed.
When changing the filter element, the oil inside of
the filter element, should be examined for deposits
of metal cuttings, which is present, could indicate
excessive wear in some of the system components.
Suction Filter
Suction filter – Item 11. A 100 mesh strainer is located
within the hydraulic oil reservoir and filters the pump
suction flow.
The filter should be cleaned at the time interval shown in
the maintenance schedule chart, using Kerosene, fuel oil
or other solvent and a soft bristled brush.
Inspect the filter wire cloth for damage. Holes in
the filter cloth leak dirt into the pump and other vital
hydraulic components. If element is damaged, replace.
When the filter has been thoroughly cleaned, reinstall
in suction line and tighten securely.
Slide Pads
Slide pads – Item 12. Check slide pads for excessive
wear and replace as required. Slide pads do not re-
quire lubrication.
Battery
Battery – Item 13. The battery will have longer life if the
water level is maintained and they are kept charged.
The engine 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.
Danger
Lead-acid batteries produce flammable and explo-
sive gases. Never allow smoking, flames or sparks
around batteries. Lead-acid batteries contain
sulfuric acid which will damage eyes or skin on
contact. When working around batteries, always
wear a face shield to avoid acid in eyes.
If acid contacts eyes, flush immediately with clear
water and get medical attention. Wear rubber gloves
and protective clothing to keep acid off skin, if acid
contacts skin, wash off immediately with clear water.
