Maintenance – 16 S2646/S3246
Return Filter
Return filter – Item 5. The hydraulic oil return filter is
mounted in the right hand tray close to the hydraulic oil
reservoir.
The filter element is a throwaway type filter and should
be changed after the initial break-in period (approximately
50 hours operation time).
Check the filter condition during the Frequent Inspection
and Maintenance 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 if present, could indicate excessive wear
in some of the system components.
Tray Hinges and Latches
Tray hinges and latches – Item 6. Lubricate using pow-
dered graphite following the Frequent Inspection and Main-
tenance schedule.
After lubricating, remove any excess so it will not collect
dirt and debris.
Slide Pads
Slide pads – Item 7. Check slide pads for excessive wear
and replace as required. Slide pads do not require lubri-
cation.
Scissor Arm Bearings
Scissor arm bearings – Item 8. Scissor arm bearings are
self lubricating. Check bearings for signs of damage and
excessive wear as outlined in the maintenance sched-
ule. Do not lubricate scissor arm bearings.
Batteries
Batteries – Item 9. The batteries and battery cables should
be checked to assure that the connections are tight and
free of corrosion. Fluid level should be maintained to as-
sure that the batteries will maintain proper charge.
Check the batteries specific gravity per the maintenance
schedule.
The batteries are enclosed within a tray located on the
side of the machine. For access to the batteries when
the machine is lowered, position the machine on a hard
level surface, unlatch and open tray.
A
Warning
Battery acid can damage the skin and eyes. Seri-
ous infection or reaction can result if medical treat-
ment is not given immediately. Wear face and eye
protection when working near the batteries.
Wear rubber gloves and protective clothing to keep acid
off skin, if acid contacts skin, wash off immediately with
clear water.
Lead-acid batteries produce flammable and explosive
gases. Never allow smoking, flames or sparks around
batteries.
Battery Care and Maintenance
The following information about battery care and mainte-
nance was supplied by Interstate Batteries and is re-
printed here with their permission.
1. New batteries need to be cycled several times be-
fore 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 prac-
tice.
3. The deeper the discharge, the fewer number of cycles
a lead-acid battery will deliver. Deep discharges de-
teriorate 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 batter-
ies 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 electro-
lyte in a lead-acid battery causes damage to the ex-
posed 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 charging
unless the plates are exposed before charging. If
exposed before charging, the plates should be cov-
ered 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 full charged battery will give you the best and long-
est service. Be sure the batteries are fully charged
before testing or using. A fully charged battery, with-
out a drain or load, after the surface charge has dis-
sipated, is 6.35 volts for a 6 volt battery.
