CHECK HYDRAULIC LINES
Check hydraulic lines after every 100 hours of
operation. Inspect for wear, cracks, loose connections,
leaks, etc. If hydraulic components require service,
stop engine, raise lift arms, engage cylinder lock (see
Operation)
and move all hydraulic controls in both
directions before any disassembly. Repair hoses as
needed. Hydraulic hoses should be replaced as wear
dictates.
CHECK ENGINE OIL LEVEL - Gasoline
Check engine oil level before each use. See Engine
Manual for detailed instructions.
CHECK ENGINE OIL LEVEL - Diesel
Check the engine oil level before each use. Check
before starting or more than five minutes after stopping
the unit. See Engine Manual for detailed instructions.
CHANGE ENGINE OIL - Gasoline
Change oil after every 25 operating hours. Change
more frequently when operating conditions are
extremely dusty. See Engine Manual for detailed
instructions.
The engine has a drain hose permanently attached to
the engine sump to facilitate draining of the engine oil.
CHANGE ENGINE OIL - Diesel
Change oil after the first 25 hours of operation and
every 50 hours thereafter. See Engine Manual for
detailed instructions.
CHANGE ENGINE OIL FILTER
Replace the oil filter every 25 hours, or each time the
engine oil is changed. See Engine Manual for detailed
instructions.
CHECK TRACTION DRIVE CHAIN TENSION
Check the drive chain tension after the first 8 hours of
operation and every 100 hours thereafter.
IMPORTANT:
If conditions are sandy, additional slack
will improve chain performance.
Each front hub is direct-coupled to a hydraulic motor.
The rear hubs are mounted on a fixed axle with the
hubs running on tapered rolled bearings. The front hub
drives are connected to the rear hubs by a roller chain.
A sliding chain tensioner takes up slack in the chain.
The chain tensioner is self compensating for direction
of travel. Each of the two roller chains are fitted with
two “half links” that can be removed to shorten the
chain as wear and slack increase.
To check chain tension:
1. Place the unit on jackstands. Remove the wheels
from the unit.
2. Remove the three hex head bolts and two nuts that
secure each chain guard. Remove the guards.
3. On each side, check chain for proper slack by
lifting the chain tensioner up by hand. If the top
plastic slider of the chain tensioner comes within
1/2” (12 mm) of the main frame above it, the chain
is too slack.
4. If slack is correct in both chains, reinstall chain
guard. If chain(s) are too slack, increase chain
tension.
WARNING:
HYDRAULIC FLUID UNDER
PRESSURE can penetrate skin and cause
severe burns that can result in death or
serious injury.
ALWAYS keep body and hands away from pin
holes or nozzles which eject hydraulic fluid
under pressure. ALWAYS use paper or
cardboard and not hands to search for leaks.
KNOW that all hydraulic fluid connections are
tight and all hydraulic hoses and lines are in
good condition BEFORE applying pressure to
system.
Foreign fluid injected into skin must be
surgically removed within a few hours by a
doctor familiar with this form of injury or
gangrene may result.
