DUERR PRO/20 - MAINTENANCE PROCEDURES; HYDRAULIC SYSTEM MAINTENANCE

I
MAINTENANCE
WARNING
Always stop the engine and dis¬
connect the spark plug wire before
performing any maintenance or
adjustments.
RESERVOIR FLUID
Check the hydraulic fluid level in the log splitter
reservoir tank before each use. Fluid level sho jld be
1-1/2" to 2" from the top of the tank.
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 tho fluid
into a suitable container. Refill using only 10 V/eight
AW type fluid or Dexron II automatic transmission
fluid, as instructed in the "Initial Preparation' sec¬
tion 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 work is perform¬
ed on the tank, hydraulic pump or
valve. Contaminants in the fluid will
damage the hydraulic components.
A
WARNING
Use extreme caution when working
with kerosene, as it is an extremely
flammable fluid.
HOSE 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 return hose
at least once a season.
ENGINE
Change the engine oil after first 5 hours of opera¬
tion. Thereafter, change every 25 hours. Check
engine oil level every 5 hours, or each time the log
splitter is used. Service air cleaner every 25 hours.
Refer to separate engine manual for complete instruc¬
tions for care and maintenance of the engine.
FLEXIBLE PUMP COUPLER
The flexible pump coupler is a nylon "spider" insert,
located between the pump and engine shaft. The
alignment is very critical. Over a period of time, the
coupler will harden and deteriorate. To replace,
remove the engine, slide it back and replace the
coupler. Do not loosen or remove pump. Replace
engine, leaving engine mounting bolts loose. Align
coupler, then tighten engine bolts. Make certain
coupler is tight.
For a replacement flexible pump coupler, order pa-"
number 717-0891.
TIRE PRESSURE
Check sidewall of tire for manufacturer's recommend¬
ed maximum tire pressure. If this information does
not appear on your tire, maximum tire pressure under
any circumstances is 30 p.s.i. Equal pressure should
be maintained on both tires.
HYDRAULIC FILTER
Change the hydraulic filter every 50 hours of c pera-
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 contacts
the splitting wedge with engine oil before each use
to obtain years of service. However, normal we sr will
occur. The wedge plate on the log splitter is design¬
ed so the gibs on the side of the wedge plats can
be easily removed and rotated and/or turned ov er for
even wear. Make certain to readjust the adjusiment
bolts so wedge moves freely, but no excess npace
exists between the wedge plate and beam.
INSTALLATION OF TIRE TO RIM
WARNING
The following precedure must be
followed when removing or installing
a tire to the rim.
1. Be certain rim is clean and free of rust.
2. Lubricate both the tire and rim generously.
3. Never inflate to over 30 p.s.i. to seat beao„.
Excessive pressure when seating beads may
cause tire/rim assembly to burst with force
sufficient to cause serious injury.
