SPARK PLUG MAINTENANCE AND REPLACEMENT
Refer to the Specifi cations for spark plug type and gap specifi cations.
Check and clean spark plugs every 200 hours. Replace plugs every
500 hours.
To prevent cross threading the spark plug, always thread it in by hand
until it seats. If the spark plug is being reused, turn it with a wrench
and additional 1/4 turn. If the spark plug is new, turn it an additional 3/8
to 1/2 turn. If you have a torque wrench, tighten a new spark plug to
11.8-14.7 N-m (120-150 Kg/cm) (8.7-10.9 ft/lb).
CHECKING BATTERIES
Every 50 hours or once a month check the fl uid level of the battery.
Refi ll with distilled water if levels are low.
Battery gas is explosive. Wear safety glasses and do
not smoke while servicing batteries. Lead acid
batteries give off a highly explosive hydrogen gas
which can be ignited by fl ame, electrical arcing or
smoking.
If the battery is to be replaced, disconnect the
negative cable fi rst, and reconnect it last.
Adjustments
CARBURETOR ADJUSTMENTS
These engines have precision-manufactured carburetors which are not
adjustable.
Engine Speed Solenoid (Optional)
Normally, the engine speed does not require any adjustment. These
instructions are for the equipment manufacturer in setting up and
adjusting the equipment.
The speed control solenoid monitors the rate of the load and automati-
cally adjusts the engine to the appropriate idle speed.
To adjust the speed control solenoid:
1 Run the engine with no load until the engine control times out
(about 15 seconds) and energizes the solenoid.
2 Adjust engine to 2200 RPM by loosening the two slotted screws
retaining the solenoid.
3 Slide solenoid forward to increase the speed, or backwards to
decrease the speed.
4 Retighten the two screws.
Following reassembly of either the carburetor or intake manifold, re-
align the governor arm on the governor shaft BEFORE making speed
adjustments to compensate for the slightly different alignment of parts.
