WARNING:

 

When  servicing,  use  only  identical  replacement  parts. 
Use  of  any  other  parts  may  create  a  hazard  or  cause 
product  damage.

 

 

 

WARNING:

 

Only the parts shown on the parts list are intended to be 
repaired or replaced by the customer. All other parts 
should be replaced at an Authorized Service Center.

 

 
 
GENERAL MAINTENANCE

 

Avoid  using  solvents  when  cleaning  plastic  parts.  Most 
plastics  are  susceptible  to  damage  from  various  types  of 
commercial solvents and may be damaged by their use. Use 
clean wipes to remove dirt, dust, lubricant, grease, etc.

 

 

 
WARNING:

 

Do not at any time let brake fluids,  gasoline, petroleum- 
based products,  penetrating lubricants, etc., come in con- 
tact with plastic parts. Chemicals can damage, weaken or 
destroy plastic which may result in serious personal injury.

 

 

 
SHARPENING THE  WEDGE

 

After using the log splitter for some time, it may be necessary 
to sharpen the wedge. Using a fine-toothed  file, smooth any 
burrs or crushed areas along the cutting  edge. 

 

LUBRICATION

 

All of the bearings in this tool are lubricated with a sufficient 
amount of high grade lubricant  for the life of the unit under 
normal  operating  conditions. 

Therefore,  no  further 

lubrication is required on the bearings.

 

 

 
 
 
 
 
 

REPLACING HYDRAULIC  OIL

 

See FIGURES 6, 7, 8, 9.

 

The  hydraulic  oil  in  the  log  splitter  should  be  changed 
every 100 hours of use. 

 

Unplug the log splitter. 

 

Position the log splitter  so that the oil drain bolt is 
positioned lower than the opposite side of the 
machine. Ensure that the log splitter is tilted to an 
angle of at least 30 degrees. The log splitter should 
be placed securely.  

 

Using 

a 6mm hex key, remove the oil drain bolt and 

disconnect the vent plug. 

 

Drain the  hydraulic 

oil  from  the  oil  tank  into  a four 

liter capacity container.

 

 

Once the oil has drained  from  the oil tank, turn 
the log splitter  on the end with the wheels. 

 

Refill the  oil  tank  with  fresh hydraulic  oil  (3.2 liters 
or 3.4 quarts). 

 

Place the cleaned dipstick  into the oil tank. Remove 
and check the oil level. 

 

Start the motor and cycle the ram several times to 
remove excess air from the reservoir.   

 

NOTE: 

The oil level should be between the two grooves 

around the bottom  of the dipstick  as shown in 

FIGURE 

7. 

 

 

Use AW32 hydraulic fluid. 

 

Replace oil drain bolt. Tighten securely.

 

 

Dispose old oil at an oil recycling center.

 

 

Refer to the oil tag for additional details.
