engine tocoolbeforestodnginanyenclosure.

• Always storegasolinein anapproved,tightly

sealed container.Storethe containerina cool,

dry place. Do notstorein a buildingwhere

ignitionsourcesare present.

• To reducefire hazard, keep engine free ofgrass,

leaves, woodchips,and excessivegreaseand

oil.

• The hydraulicsystemofyourlogsplitterrequires

carefulinspection,along withthe mechanical

parts.Be suretoreplacefrayed, kinked,or

otherwisedamagedhydrauliccomponents.

Fluid escapingfrom a verysmallholecan be

almost invisible. Do notcheck for leakswith your

hand. Escaping fluid under pressure can have

sufficient force to penetrate skin, causing

• serious personal injury. Leaks can be located by

passing a piece of cardboard or wood over the

suspected leak and looking for discoloration.

Should it become necessary to loosen or

remove any hydraulic fitting or line, be sure to

relieve all pressurebyshutting off the engine

and moving the control handle back and forth

several times.

Do not remove the cap from the hydraulic tank or

reservoir while your log splitterisrunning. Hot oil

under pressure couldcause injury.

The pressure relief valve on your splitter is

preset at the factory. Do not adjust the valve.

Only a qualified service technician should

perform this adjustment.

• Completely drain fuel tank prior to storage. This

guards against accumulation offuel fumes

whichcouldresultin a fire hazard.

Never store log splitter outside without a

waterproof cover. Rain will cause rust on the

inside of the cylinder.

Important Information

Always:

Use clean fluid and check fluid level regularly.

Use Dexron III Automatic Transmission Fluid or

10W non-foaming hydraulic fluid.

Use a filter (clean or replace regulady).
