MAINTENANCE

WARNING:

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

WARNING:

Always wear safety goggles or safety glasses with side 
shields  during  power  tool  operation  or  when  blowing 
dust. If operation is dusty, also wear a dust mask.

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 cloths to remove dirt, dust, oil, grease, etc.

WARNING:

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

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 lubrica-
tion is required.

REPLACING HYDRAULIC OIL

See Figures 12 - 13.

The  hydraulic  oil  in  the  log  splitter  needs  to  be  changed 
every 150 hours of use.

n

  Unplug the log splitter.

n

  Position the log splitter so that the motor end is slightly 

higher than the oil drain plug.

n

  Using an 8 mm hex key, remove the oil drain bolt.

n

  Drain the hydraulic oil from the oil tank into a four liter 

capacity container.

n

  Once the oil has drained from the oil tank, turn the log 

splitter on the end with the wheels.

n

  Refill the oil tank with fresh hydraulic oil (3.7 quarts or 

118 oz.). The following hydraulic oils are recommended:

     - SHELL Tellus 22
     - MOBIL DTE 11
     - ARAL Vitam GF 22
     - BP Energol HLP-HM 22

n

  Place the cleaned dipstick into the oil tank. Remove and 

check the oil level.

NOTE:

 The oil level should be between the two grooves 

around the bottom of the dipstick as shown in figure 5.

n

  Replace oil drain bolt. Tighten securely.

n

  Dispose old oil at an oil recycling center.

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.
