Hydraulic Oil Return Filter
Return filter – Item 9. Tthe hydraulic oil return filter is
mounted inside of the 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 may be 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 90° F (32° C).
A
Warning
Use extreme caution while observing the condition
indicator because of the motion of the drive wheels.
The condition indicator is best observed from out-
side of the tract of the vehicle wheels to avoid pos-
sible personal injury or machine damage.
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.
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.
Batteries
Batteries – Item 12. Batteries 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.
A
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. 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.
6. A fully charged battery will give you the best and lon
-
gest service. Be sure the batteries are fully charged
before testing or using. A fully charged battery,
without a drain or load, after the surface charge has
dissipated, is 6.35 volts for a 6 volt battery.
7. 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.
8. Battery chargers should be sized to fully charge
batteries in an eight hour period. Chargers should
be kept in proper operating condition.
9. 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
