Maintenance – 18 A62JRT – 104897-000
Note
If it becomes necessary to add or use an oil other than
the recommended fluid, it is important that it be compat
-
ible and equivalent to the factory fill. Local oil suppliers
can generally furnish this information.
If questions still remain, contact Snorkel Customer Ser
-
vice 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 recom
-
mended intervals.
Hydraulic Oil Return Filter
Return filter – Item 8. The hydraulic oil return filter is
located on the hydraulic reservoir behind the door on
the right side of the turntable
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 condition should be checked at the 90 day or
150 hour Preventive Inspection Maintenance interval or
more frequently under extreme working conditions.
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 Strainer
Suction strainer – Item 9. Two 100 mesh strainers are
located within the hydraulic oil reservoir, one on the
inlet and one on the outlet, and filters the pump suction
flow.
The strainers 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.
Door Hinges and Latches
Door hinges and latches – Item 10. After lubricating,
remove any excess lubricant or over spray so it will not
collect dirt or debris.
Slide Pads
Slide pads – Item 11. Check slide pads for excessive
wear and replace as required. Slide pads do not require
lubrication.
Battery
Battery – Item 12. 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 sulfu-
ric 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.
Battery Care and Maintenance
The following information about battery care and main
-
tenance was supplied by Interstate Batteries and is
reprinted here with their permission.
1. New batteries need to be cycled several times before
reaching full capacity (20-50 cycles, depending on
type). Usage should be limited during this period.
2. Always recharge batteries fully, immediately after
use. Batteries perform best when they are fully
charged. More capacity and longer life will result
from this practice.
3. The deeper the discharge, the fewer number of
cycles a lead-acid battery will deliver. Deep dis
-
charges deteriorate the battery quicker than lighter
shallow cycles.
4. Battery cables should be intact and connectors kept
tight at all times. Systematic inspection is recom
-
mended.
5. Vent caps should be kept in place and tight during
vehicle operation and battery charging.
6. Batteries should be kept clean – free of dirt and cor
-
rosion – at all times. Always keep the top of batteries
clean. A film on top of the battery can cause the
current to migrate between the posts, accelerating
self discharge.
7. Never let the electrolyte level of a lead-acid battery fall
below the plates. Lack of maintaining the electrolyte
in a lead-acid battery causes damage to the exposed
portion of the plate which reduces capacity.
8. Always check electrolyte level before charging. Do
not add water to individual cells unless plates are
exposed. Batteries should be watered after charg
-
ing unless the plates are exposed before charging.
If exposed before charging, the plates should be
covered by approximately 1/8 ″ of water. Check water
level after charging. Water should be kept 1/4 ″
below
the bottom of the fill tube in the cell cover.
9. Water used to replenish batteries should be distilled
or treated to not exceed 200 T.D.S. (total dissolved
solids... parts per million). Particular care should be
taken to avoid metallic solids (iron).
10. A fully charged battery will give you the best and
longest service. Be sure the batteries are fully
charged before testing or using. A fully charged bat
-
tery, without a drain or load, after the surface charge
has dissipated, is 6.35 volts for a 6 volt battery.
11. Batteries should not be discharged below 20% of
capacity (approximately 1.8 volts per cell under
normal operating load; 1.98 volts open circuit; 1.145
specific gravity). Proper battery sizing will help avoid
excessive discharge.
12. Battery chargers should be sized to fully charge
batteries in an eight hour period. Chargers should
be kept in proper operating condition.
13. Do not use a mismatched charger of any type; i.e.,
a 12 volt charger on a 24 volt pack or a 24 volt
charger on a 12 volt pack. An undersized charger
will never get the job done, no matter how long it
tries. An oversized charger will cause excess gas
-
sing and heat that could possibly result in a battery
meltdown and/or explosion.
14. Never charge a lead-acid battery with a sealed (gel
cell) battery charger. The lead-acid battery needs
higher voltage to finish its charge. Without it the
battery will never come back to 100% and sulfation
can occur.
15. Always allow batteries to cool off after charging.
The cooling time is very important because heat
is generated during the recharge and discharge
cycles. Without the cooling time the heat grows,
accelerating grid corrosion which is one of the major
causes of battery failure. Charging practice should
enable batteries to cool before use.
16. Deep cycle batteries need to be equalized peri
-
odically. Equalizing is an extended, low current
charge performed after the normal charge cycle. It
helps keep cells in balance. Actively used batteries
should be equalized once per week. Manually timed
chargers should have the charge time extended
approximately 3 hours. Automatically controlled
chargers should be unplugged and reconnected
after completing a charge cycle.
