IMPORTANT INFORM/mON FOR LOG SPLITTER USERS
ALWAYS:
Use clean fluid and check fluid level regularly
Use Dexron II Automatic Transmission Fluid nr
10W non-foaming hydraulic fluid.
Use a filter (clean or replace regularly)
Use a breather cap on fluid reservoir
Keep end of reservoir return tube below fluid evel
Make certain pump is mounted and aligned p operly
Use a flexible “spider" type coupling betweer engine
and pump driveshafts
Keep hoses clear and unblocked
Bleed air out of hoses before operating
Flush and clean hydraulic system before star up after
any malfunction or servicing
Use “pipe dope” on all hydraulic fittings
Allow time for warmup before splitting wood
Prime the pump before initial startup by turnir g over
the engine with spark plug disconnected
Split wood with the grain (lengthwise) only
NEVER:
Use fluid below 0° F., or above 150° F.
Use a solid engine/pump coupling
Force pump when mounting
Operate through relief valve for more than several
seconds
Attempt to adjust unloading or relief valve settings
without pressure gauges
Operate with air in hydraulic system
Use Teflon tape on hydraulic fittings
Warm up engine apart from pump in cold weather
Attempt to cut wood across the grain
