This prevents accidental carriage movement which may cause serious
injury or death.
WARNING! Do not operate engine without proper and operational
spark arrester/muffler. Sparks emitted from the engine exhaust could
ignite surrounding materials, causing serious injury or death.
WARNING! Disengage the blade and remove all persons out of the
path of the blade before starting the engine. Failure to do so may result
in serious injury.
WARNING! Never operate an engine with a fuel or oil leak. The leak-
ing fuel or oil could potentially come in contact with hot surfaces and
ignite into flames.
NOTE: Always relieve all fuel pressure inside the tank prior to filling or
connecting fuel fittings. Failure to do so may result in fuel spillage.
NOTE: Disconnect the fuel tank when not in use or during transporta-
tion. Failure to do so may result in engine flooding or fuel spillage.
NOTE: Do not engage the clutch lever repeatedly without the engine
running. The engine floods when the throttle solenoid is engaged, an
accelerator pump is activated which supplies fuel to the engine carbu-
retor.
1. Turn the key switch momentarily to the start (2) position and release it to the run position
(1).
ENGINE SHUTOFF
Turn the key switch to the off (0) position.

SECTION 3 MAINTENANCE
Refer to the manufacturer’s manual for maintenance intervals and procedures unless oth-
erwise instructed in this manual. Follow the manufacturer’s recommendations for dusty
conditions.
IMPORTANT! This manual only provides information about additional
procedures or procedures to be performed at different time intervals
than found in the manufacturer's manuals. Refer to the manufacturer's
manual for complete maintenance instructions.
WARNING! Clean sawdust from all guards, vents, control
boxes, or any area where sawdust may gather after every
shift. Failure to do so may result in fire, causing death or
serious injury.
3.1 Safety
Use caution when performing maintenance or service to the engine.
DANGER! Always be aware of and take proper protective measures
against rotating shafts, pulleys, fans, etc. Always stay a safe distance
from rotating members and make sure that loose clothing or long hair
does not engage rotating members resulting in possible injury.
DANGER! Engine components can become very hot during operation.
Avoid contact with any part of a hot engine. The exhaust components
of your engine are especially hot during and following operation. Con-
tact with hot engine components can cause serious burns. Therefore,
never touch or perform service functions on a hot engine. Allow the
engine to cool sufficiently before beginning any service function.
WARNING! Remove the blade before performing any engine service.
Failure to do so may result in serious injury.
WARNING! Always wear proper and necessary safety equipment
when performing service functions. Proper safety equipment includes
eye protection, breathing protection, hand protection and foot protec-
tion.
This symbol identifies the interval (hours of operation) at which each maintenance pro-
cedure should be performed. "AR" signifies maintenance procedures which should be
performed as required.

3.2 Cooling System
Wash the engine or brush off sawdust and debris every 50 hours of operation. Clean the
grass screen, cooling fins, and external surfaces. Remove any dust, dirt or oil. See
engine manual for further instructions.
3.3 Air Cleaner
WARNING! Always wear proper and necessary safety equipment
when performing service functions. Proper safety equipment includes
eye protection, breathing protection, hand protection and foot protec-
tion.
Replace the outer air cleaner cartridge and check the inner cartridge every 250 hours of
operation or more often if operating the sawmill in dirty conditions or if engine perfor-
mance indicates a new cartridge is necessary.
CAUTION! Do not clean elements with water or compressed air. Do
not handle the inner element unless it is to be changed. Handle new
elements carefully. Contact with the element could cause damage and
prevent the filter from operating properly.
Replace the inner air cleaner cartridge every 1200 hours of operation or more often if
operating the sawmill in dirty conditions.
3.4 Fuel Filter
Replace the fuel filter every 100 hours of operation or as required for engine perfor-
mance.
3.5 Battery
Check the battery electrolyte level every 50 hours of operation. See manufacturer’s man-
ual for instructions.
DANGER! Batteries expel explosive gases. Keep sparks, flames,
burning cigarettes, or other ignition sources away at all times. Always
wear safety goggles and a face shield when working near batteries.
Failure to do so will cause serious injury.1

3-3 WM doc 9/25/19 Maintenance
WARNING! Battery posts, terminals and related accessories contain
lead and lead compounds, chemicals known to the State of California
to cause cancer and reproductive harm. Wash hands after handling.
3.6 Alternator Belt
The belt tension should be checked after the first 100 hours of operation, when the bat-
tery is not charging properly or when the alternator belt is squealing.
If the battery continues to not charge properly or the belt continues to squeal after the ini-
tial belt adjustment, replace the belt.
1. Release the blade tension and remove the blade from the sawmill if necessary. Turn the
key switch to OFF (0) and remove the key.
2. Remove the drive belt cover and alternator cover.
See Figure 3-1.
3. Use a belt tension gauge to measure the belt tension. Place the gauge on the belt at the
midpoint between the two pulleys. If the belt tension is less than 3/16” with 9 lb. of deflec-
tion, tighten the belt as described below.
4. Loosen the upper pivot, lower pivot and the adjustment bolt jam nut.
5. Turn the belt tension adjustment bolt clockwise to tighten the belt, counterclockwise to
loosen the belt. Adjust the bolt until the proper belt tension is achieved.
CAUTION! Do not overtighten the alternator belt. Damage to the alter-
nator will occur.

6. After the alternator belt has been tensioned, tighten the adjustment bolt jam nut. Tighten
the upper and lower pivots and replace the belt covers.
3.7 RPM Adjustments
WARNING! Remove the blade before performing any engine service.
Failure to do so may result in serious injury.
Check the RPM with a tachometer every 200 hours of operation.
See Table 3-1.
Before checking the RPM, make sure belt and brake strap tensions are correct (See Saw-
mill Maintenance). Also check oil, fuel, and coolant levels.
Make sure the throttle cable does not affect the engine RPM when the throttle solenoid is
disengaged. Make sure the cable is not bent or kinked. NOTE: It is important that the
above components are aligned. Proper alignment allows any slack in the cable (when
engine is idling) to slide down into the cable spring. This maintains free operation of the
cable and prevents the cable from kinking. Make sure the shoulder bolt does not rub
against the crankcase vent tube.
1. Start the engine to measure the low-end RPM.
2. Refer to the engine manual to adjust the low-end RPM.
3. Engage the throttle solenoid to throttle the engine and measure the high-end RPM. The
high-end RPM is factory-set at 3600. Readjust the throttle cable if necessary to increase
or reduce the high-end engine speed.
The throttle cable should be tensioned just enough so that the engine revs as soon as the
clutch/brake handle is engaged. NOTE: A properly adjusted throttle will extend the cable
spring 1/4” to 3/8” (6.4 - 9.5 mm) when running and have a slight amount of slack in the
cable when idling.
3.8 Miscellaneous Maintenance
Clean and inspect the spark arrester every 50 hours of operation. Replace if damaged.
Review the manufacturer's engine manual for maintenance intervals.
