Bolens 522 - Manual (Page 12)

RESERVOIR FLUID
Check the hydraulic fluid level in the log splitter reser­
voir tank before each use. Fluid level should b 51-1/2"
to 2" from the top of the tank.
Change the hydraulic fluid in the reservoir eviry 100
hours of operation. Disconnect the suction hose from
the bottom of the reservoir tank, and drain the f uid into
a suitable container. Refill using only Dexron II auto­
matic transmission fluid or 10W non-foaming h/draulic
fluid, as instructed in the “Initial Preparation” s€ ction of
this manual, page 9. Also, make certain to change the
hydraulic filter.
NOTE: Drain the fluid and flush the reservoir tank and
hoses with kerosene whenever any repair won: is per­
formed on the tank, hydraulic pump or valve. C ontami-
nants in the fluid will damage the h /draulic
components. (Should be performed by an auihorized
service dealer.)
A
WARNING: Use extreme caution when
working with kerosene, as it is an
extremeiy fiammabie fiuid.
HYDRAULIC FILTER
Change the hydraulic filter every 50 hours o1 opera­
tion. Use only a 10 micron hydraulic filter. Order part
number 723-0405.
BEAM AND SPLITTING WEDGE
Lubricate both sides of the beam where it conticts the
splitting wedge with engine oil before each use to
obtain years of service. However, normal W3ar will
occur. The wedge plate on the log splitter is d ssigned
so the gibs on the side of the wedge plate can ce eas­
ily removed and rotated and/or turned over fnr even
wear. Make certain to readjust the adjustment nolts so
wedge moves freely, but no excess space exists
between the wedge plate and beam.
HDSE CLAMPS
Check the hose clamps on the suction hose (attached
to bottom of the pump) for proper tightness before
each use. Check the hose clamps on the retu n hose
at least once a season.
ENGINE
Refer to the separate engine manuai for aii engine
maintenance instructions.
Maintain engine oii as instructed in the ssparate
engine manual packed with your unit. Read ani follow
instructions carefully.
Service air cieaner every 25 hours under normal con­
ditions. Clean every few hours under extremeiy dusty
conditions. Poor engine performance and Hooding
usually indicates that the air cleaner should oe ser­
viced. To service the air cleaner refer to the saparate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom­
mended at the start of each season; check engine
manual for correct plug type and gap specification.
Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to per­
mit proper air circulation which is essential to engine
performance and life. Be certain to remove all dirt and
combustible debris from muffler area.
FLEXIBLE PUMP CDUPLER
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 experi­
ence a loss of power.
IMPORTANT: Never hit the pump shaft in any man­
ner, as any blow will cause permanent damage to
the pump.
When replacing the flexible pump coupling, proceed
as follows. Follow the instructions carefully as the
alignment is very critical.
1. Disconnect the spark plug wire from the spark
plug, and secure it away from the spark plug.
2. Using a 1/2 inch wrench, remove three nuts and
lock washers which secure the pump to the
coupling shield. Two nuts are at the bottom
corners and one is in the top center.
3. Remove the pump.
4. Rotate the engine by pulling starter handle until
engine coupling half set screw is at bottom.
Loosen set screw using 7/64 inch Allen wrench.
Slide coupling half off of engine shaft.
5. Loosen set screw on pump coupling half, and
remove coupling half.
6. 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.
7. Install pump coupling half and key on pump shaft.
Rotate coupling half until set screw faces down.
Do not tighten set screw.
8. Install nylon “spider” onto engine coupling half.
9. Align pump coupling half with nylon “spider” by
rotating engine using starter handle. Slide cou­
pling half into place while guiding three mounting
bolts through holes in pump support bracket.
10. Secure with nuts and washers removed earlier.
