Hex Bolts

Bolts

FIGURE 18.

• Loosen the three hex bolts on top of the slide plate

(beneath the splitting wedge).

• Back the two adjustment bolts on the side of the slide

plate out

slowly

until the wedge assembly will slide

on the beam. Tighten the lock nuts securely against

the base of the slide plate to hold the bolts in this

position.

• Retighten the three hex bolts on top of the slide plate.

CARBURETOR ADJUSTMENT

A

WARNING: IF ANY ADJUSTMENTS ARE
MADE TO THE ENGINE WHILE THE
ENGINE IS RUNNING (e.g. CAR­
BURETOR), KEEP CLEAR OF ALL MOV­
ING PARTS. BE CAREFUL OF HEATED

SURFACES AND MUFFLER.

Minor carburetor adjustment may be required to com­

pensate for differences in fuel, temperature, altitude or
load.

NOTE:

A DIRTY AIR CLEANER WILL CAUSE ENGINE

TO

RUN

ROUGH.

BE

CERTAIN

ARE

SATISFACTORY

FOR

MOST

AP­

PLICATIONS AND CONDITIONS.

Never attempt to change maximum engine speed. It

is pre-set at the factory and shouid be changed only
by a qualified service technician who has the necessary

equipment.

The Carburetor may need re-adjusting if engine lacks

power or does not idle properly. If adjustments are

needed, proceed as follows.

for best performance under load.

Place throttle control in IDLE position:

is

necessary.

If engine idles too fast, turn idle speed adjusting

screw counterclockwise (

until slower speed

is obtained.

If engine dies, turn idle speed adjusting screw

turn clockwise (/^ ). Place throttle control in

FAST position and restart engine.

d.

Move throttle control to IDLE position. If engine

does not idle, repeat step c.

• Test the engine by splitting. If engine tends to stall

or die out, it usually indicates that the mixture is
slightly lean and it may be necessary to open (

f ~ \

)

the needle valve slightly to provide a richer mixture.

This richer mixture may cause a slight unevenness
in idling.

MAINTENANCE

A

WARNING: ALWAYS STOP THE ENGINE
AND DISCONNECT THE SPARK PLUG
WIRE BEFORE PERFORMING ANY
MAINTENANCE OR ADJUSTMENTS.

RESERVOIR FLUID

Check the hydraulic fluid level in the log splitter reser­

voir tank before each use. Fluid level should 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 the fluid in-
