SECTION 6: MAINTAINING YOUR LOG SPLITTER
WARNING: Before cleaning, lubricating,
repairing, or inspecting, disengage the
control lever and stop engine. Disconnect
the spark plug wire and ground it against
the engine to prevent unintended starting.
Hydraulic Fluid
•
Check the hydraulic fluid level in the log splitter
reservoir tank before each use. Maintain fluid level
within the range specified on the dipstick at all
times.
•
Change the hydraulic fluid in the reservoir every
100 hours of operation. Disconnect the suction
hose from the bottom of the reservoir tank and drain
the fluid into a suitable container. Refill using only
Dexron III automatic transmission fluid or 10W AW
hydraulic fluid.
NOTE: Drain the fluid and flush the reservoir tank and
hoses with kerosene whenever any repair work is
performed on the tank, hydraulic pump or valve.
Contaminants in the fluid will damage the hydraulic
components. Any repair to the hydraulic components
shopuld be performed by a authorized service center.
WARNING: Use extreme caution when
working with kerosene. It is an extremely
flammable fluid.
Hydraulic Filter
Change the hydraulic filter every 50 hours of operation.
Use only a 10 micron hydraulic filter. Order part number
723-0405.
Beam And Splitting Wedge
Lubricate both sides of the beam (where it comes into
contact with the splitting wedge) before each use with
engine oil. The wedge plate on the log splitter is
designed so the gibs on the side of the wedge plate can
be removed and rotated and/or turned over for even
wear.Make certain to readjust the adjustment bolts so
wedge moves freely, but no excess space exists
between the wedge plate and beam.
Hose Clamps
Check the hose clamps on the suction hose (attached
to side of the pump) for proper tightness before each
use. Check the hose clamps on the return hose at least
once a season.
Engine
Refer to the separate engine manual for all engine
maintenance instructions.
Flexible Pump Coupler
The flexible pump coupler is a nylon “spider” insert,
located between the pump and engine shaft. Over a
period of time, the coupler will harden and deteriorate.
Replacement is needed if you detect vibration or noise
coming from the area between the engine and the
pump. If the coupler fails completely, you will
experience a loss of power.
IMPORTANT:
Never hit the engine shaft in any manner,
as a blow will cause permanent damage to the engine.
When replacing the flexible pump coupler, proceed as
follows:
•
Remove three nuts and lock washers that secure
the pump to the coupling shield. Two nuts are at the
bottom corners and one is in the top center.
•
Remove the pump.
•
Rotate the engine by pulling starter handle until
engine coupling half set screw is at bottom. Loosen
set screw using allen wrench and slide coupling half
off of engine shaft.
•
Loosen set screw on pump coupling half and
remove coupling half.
•
Slide new engine coupling half onto the engine
shaft until the end of the shaft is flush with the inner
portion of the coupling half. (There must be space
between end of the engine support bracket and
coupling half). Tighten set screw.
•
Install pump coupling half and key on pump shaft.
Rotate coupling half until set screw faces down. Do
not tighten set screw.
•
Install nylon “spider” onto engine coupling half.
•
Align pump coupling half with nylon “spider” by
rotating engine using starter handle. Slide coupling
half into place while guiding three mounting bolts
through holes in pump support bracket.
•
Secure with nuts and washers removed earlier.
•
Set .010” to .060” clearance between the nylon
“spider” and the engine coupling half by sliding a
matchbook cover between the nylon “spider” and
the engine coupling half and moving pump coupling
half as needed. Secure pump coupling half with set
screw. See Figure 17.
NOTE: Make certain proper clearance is obtained
before tightening set screw.
•
Reattach spark plug wire to spark plug.
