MTD 242-632-000 - Manual (Page 12)

The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is ecom-
mended at the start of each season; check engine
manual for correct plug type and gap specificat on.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is esseitial to
engine performance and life. Be certain to rerr ove all
dirt and combustible debris from muffler area.
PUMP
FLEXIBLE PUMP COUPLER
The flexible pump coupler is a nylon “spider” insert,
located between the pump and engine sha 't. The
alignment is very critical. Over a period of tine, the
coupler will harden and deteriorate. For a re place­
ment flexible pump coupler, order part number 717-
0891.
IMPORTANT: Never hit the pump shaft in anf man­
ner, as any blow will cause permanent damage to the
pump.
When replacing the flexible pump coupling, p oceed
as follows.
1. Place the coupling half onto the engine shaft.
Make certain there is clearance between tf e cou­
pling half and the engine. Tighten the set screw.
2. Mount the pump onto the coupling support brack­
et. Tighten securely.
3. Carefully slide coupling half onto pump shaft
(make certain set screw is loose). Slide tie key
into place on the shaft.
4. Install the nylon “spider” insert into coupling half
on the engine shaft.
5. Place the coupling shield in position on the hex
bolts. Rotate the keyway on the pump shaft so it
is toward the bottom.
6 . Attach the coupling support bracket to the hex
bolts, carefully sliding the coupling half o\ er the
“spider” insert. Secure coupling shield and cou­
pling support bracket with lock washers and hex
nuts. Tighten securely.
7. Adjust the two coupling halves (steel) so t lere is
between . 010 ” and .060” clearance between the
two halves (at least the thickness of a matchbook
cover, up to 1/16” maximum). See figure 17.
Tighten the set screw in the coupling half on the
pump shaft.
NOTE: Make certain proper clearance is ob tained
before tightening set screw.
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.
INSTALLATION OF TIRE TO RIM
A
WARNING: The following procedure 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 beads.
Excessive pressure when seating beads may
cause tire/rim assembly to burst with force suffi­
cient to cause serious injury.
OFF-SEASON STORAGE
If the log splitter will not be used for a period longer
than 30 days, the following steps should be taken to
prepare the log splitter for storage.
1. Clean the engine and the entire log splitter thor­
oughly.
2. Refer to the engine manual for correct engine
storage instructions. Follow instructions care­
fully.
3. Wipe unit with an oiled rag to prevent rust, espe­
cially wedge and beam.
4. Store unit in a clean, dry area. Do not store next
to corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rustproof the equipment by coating with a
light oil or silicone.
