SECTION 1 OPERATION

1.1 Starting The Engine

Control Lights

See Figure 1-1. The following indicator lights are located on the sawmill control panel.

Alternator Charge Indicator: Lights up if the alternator is not charging the battery.

Engine Temperature Indicator: Lights up if the engine is overheating. A circuit breaker

assembly in the engine harness will shut the engine off if the engine overheats. Turn the

key switch off and allow the engine to cool for a period of time before restarting. If the

overheating condition persists, stop operating the engine until the condition is corrected.

The engine will automatically switch to low idle if an overheating condition occurs.

Oil Indicator: Lights up if the oil pressure is too low.

Glow Plug Indicator: Lights up after the key has been turned to the on (#1) position.

Operation doc062309 1-2

Engine Start

DANGER! Always be sure the blade is disengaged and all

persons are out of the path of the blade before starting the

engine. Failure to do so will result in serious injury.

DANGER! Operate your engine/machine only in well venti-

lated areas. The exhaust gases of your engine can cause

nausea, delirium and potentially death unless adequate

ventilation is present.

DANGER! Never operate an engine with a fuel or oil leak.

The leaking fuel or oil could potentially come in contact with

hot surfaces and ignite into flames.

WARNING! Be sure the power feed switch is in the neutral

position before turning the key switch to the on (#1) or

accessory (#3) position. 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.

CAUTION! Do not crank starter for more than 7 seconds at

one time during starting attempts. Damage to the engine

may result.

CAUTION! Let cool engine idle for 2 minutes before apply-

ing load to prevent engine damage.

1. See the engine manufacturer’s manual for lubricating oil recommendations for specific

temperature ranges.

2. Use a best quality diesel fuel for below freezing starting.

3. Turn the key switch on the control panel to the on (#1) position.

4. Wait until the glow plug indicator goes out.

5. Turn the key switch to the start (#2) position and release.

SECTION 2 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 dif-

ferent time intervals than found in the manufacturer's manu-

als. Refer to the manufacturer's manual for complete

maintenance instructions.

2.1 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 dur-

ing and following operation. Contact with hot engine com-

ponents 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 protec-

tion, hand protection and foot protection.

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.

2.2 Cooling System

Clean the radiator fins every 8 hours of operation. Spray the radiator with water from a

hose or compressed air to clean sawdust from the radiator fins. Do not use a pressure

sprayer.

CAUTION! Failure to keep the radiator fins clear of sawdust

and/or dirt may cause the engine to overheat resulting in

damage to the engine.

CAUTION! Do not spray the radiator with water when the

engine is hot.

CAUTION! Do not open the radiator cap or reservoir cap

when the engine is hot.

Every 8 hours of operation check the coolant level on the coolant reservoir. When engine

is cold the coolant level should be above the LOW level.

For the aluminium radiator use only glycol solution (1l. of glycol concentrate for 1l. of dis-

2.3 Fuel Filter

See Figure 2-1. Replace the primary fuel filter cartridge every 1500 hours or one year of

operation. After replacing the filter cartridge, loosen the air bleed screw and operate the

fuel pump bail until fuel begins to flow from the valve and is free of air bubbles. Tighten

the bleed screw. Inspect the water separator bowl periodically and drain the bowl as

required by turning the drain cap counterclockwise as viewed from the bottom.
