Hydraulic Filter
Change the hydraulic filter every 50 hours of operation. Use only a 10 micron hydraulic spin-on filter, or buy from an authorized
dealer. Order part # 51 in Exploded Diagram.
Flexible Pump Coupler
The flexible pump coupler, located between the pump and the engine shaft, has a nylon “spider” insert. Over time, the insert will
harden and deteriorate. If you detect vibration or noise coming from the area between the engine and the pump, contact us at
www.DRpower.com or call toll-free 1-800-DR-OWNER (376-9637) for assistance. Change a new coupler immediately (refer to the
pump assembly STEP 4 in Page 12), if the coupler fails completely, you will experience a loss of hydraulic power.
Hydraulic Fluid
Check the hydraulic fluid level in the log splitter reservoir tank before each use. Maintain the fluid level within the range specified
on the dipstick at all times.
Change the hydraulic fluid in the reservoir every 100 hours of operation. The filter should also be changed with each hydraulic fluid
change. Follow the steps below:
1. Place a suitable oil collection container under the tank. Allow the fluid to drain into the container.
Note: The hydraulic system has a capacity of 4 gallons of hydraulic fluid for 22 Ton and 28 Ton; and 5 gallons for 34 Ton.
2. After draining, screw on the oil drain screw and tighten.
3. Refill the reservoir tank (Please follow the steps in Page 20 - 21 to fill the tank, and repel the air in the tank). The fluid
should be just touching the end portion of the dipstick.
4. Maintain the fluid level within the range specified at all times (Figure 26).
Note: When checking the fluid, always make sure to install the dipstick and push it down fully.
Note: Always dispose of any used hydraulic fluid and engine oil at approved recycling centers only. Contaminants in the fluid may
damage the hydraulic components.
Beam and Splitting Wedge
Lubricate top, sides and bottom of the beam and where it comes into contact with the splitting wedge with engine oil before each
use.
If the wedge becomes dull or nicked, it can be sharpened.
