STEP 6: Add Engine Oil
1. Make sure the log splitter is on a level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Refer to the separate owner’s engine manual for the amount needed of SAE10W-30 engine oil;
replace oil fill cap/dipstick.
4. Check engine oil level daily and add as needed.
NOTE: During the break-in period check the engine oil level often.
STEP 7: Add Hydraulic Oil
1. The log splitter needs to be cold on a flat level surface before adding the hydraulic oil.
2. Remove the oil cap from the hydraulic reservoir.
3. Add
2.5 gallons of hydraulic oil AW32, AW46 & universal hydraulic oil are all acceptable types of
fluid. Automatic transmission fluid should be used when operating in temperatures below
32 degrees (all units are tested and have excess oil in the ram).
4. Check the hydraulic oil level.
5. Start engine and use the control lever to extend and retract wedge several times to remove
air from the lines.
6. With the wedge retracted, check hydraulic oil level again and fill if necessary.
7. Do not thread in the dipstick when checking the
hydraulic oil level. The hydraulic oil should
be checked when the machine is cold and level. The oil should be kept above the “COLD”
line. Never fill the oil level above the “HOT” line when the unit is cold. This will result in oil
being expelled through the vent on the dipstick.
WARNING
DO NOT remove the hydraulic oil fill cap when the engine is running or hot. Hot oil can escape,
causing severe burns. Always allow the log splitter to cool completely before removing the hydraulic
oil cap.
High fluid pressure and temperatures are created in the hydraulic log splitters. Hydraulic fluid will
escape through a pin-size hole opening and can puncture skin and cause severe blood poisoning.
Inspect hydraulic system regularly for possible leaks. Never check for leaks with your hand while
the system is pressurized. Seek medical attention immediately if injured by escaping fluid.
Make sure all fittings are tight and secure before applying press
ure. Relieve system pressure before
servicing.
Make sure the hydraulic hoses do not touch any hot surfaces or cutting areas.
Hoses need to be positioned were they are clear from the engine and cutting wedge. To avoid serious
bodily injury always inspect the hoses before operating the log splitter.
CAUTION
DO NOT attempt to crank or start the engine before it has been properly filled with the recommended
type and amount of oil. Damage to the log splitter as a result of failure to follow these instructions will
void your warranty.
- 11 -
STEP 8: Add Gasoline to the Engine
1. Use only clean, fresh, regular unleaded fuel with a minimum 87 octane rating.
2. DO NOT mix oil with fuel.
3. Remove the fuel cap, and slowly add fuel to the tank. DO NOT overfill, allow approximately ¼ inch
of space for fuel expansion.
4. Screw on the fuel cap and wipe away any spilled fuel.
DANGER
Log splitter engine exhaust contains carbon monoxide, a colorless, odorless, poison gas. Breathing
carbon monoxide will cause nausea, dizziness, fainting or death. If you start to feel dizzy or weak, get
to fresh air immediately.
Operate log splitter outdoors only in a well-ventilated area.
DO NOT operate the log splitter inside any building, enclosure or compartment.
DO
NOT allow exhaust fumes to enter a confined area through windows, doors, vents or other
openings.
DANGER CARBON MONOXIDE, using a log splitter indoors CAN KILL YOU IN MINUTES.
CAUTION
Fuel and fuel vapors are highly flammable and extremely explosive.
Fire or explosion can cause severe burns or death.
Unintentional startup can result in entanglement, traumatic amputation or laceration.
Only use regular unleaded gasoline with a minimum 87 octane rating.
DO NOT mix oil and gasoline together.
Fill tank approximately ¼” below the top of the tank to allow for fuel expansion.
DO NOT fill fuel tank indoors or when the engine is running or hot.
DO NOT light cigarettes or smoke when filling the fuel tank.
