SAFETY PRECAUTIONS

WARNING

•Have a qualified technician do the maintenance and troubleshooting work.

•Turn the engine off before working inside the machine.

•Remove guards only when necessary and replace them when the maintenance requiring their removal is complete.

•Always use the greatest care when working near moving parts.

------------------------------------------------------------------------

Read the Safety Precautions in front of this manual and the engine instruction manual before working on this machine.

Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, cloth- ing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repair- ing the equipment.

ROUTINE AND PERIODIC

MAINTENANCE

DAILY

a. Check the crankcase oil level .

b. Refill the fuel tank to minimize moisture condensa- tion in the tank.

c. Open the water drain valve located on the bottom of the water separator element 1 or 2 turns and allow to drain into a container suitable for diesel fuel for 2 to 3 seconds. Repeat the above drainage procedure until diesel fuel is detected in the container.

WEEKLY

Blow out the machine with low pressure air periodical- ly. In particularly dirty locations, this may be required once a week.

ENGINE MAINTENANCE

Refer to the “Periodic Checks” section of the Engine Operator’s Manual for the recommended maintenance schedule of the following:

a)Engine Oil and Filter

b)Air Cleaner

c)Fuel Filter - and Delivery System

d)Cooling Blower Belt

e)Battery

f)Cooling System

Refer to Table D.1 at the end of this section for various engine maintenance components.

AIR FILTER

CAUTION

EXCESSIVE AIR FILTER RESTRICTION WILL RESULT IN REDUCED ENGINE LIFE.

------------------------------------------------------------------------

The air filter element is a dry cartridge type. It can be cleaned and reused; however, damaged elements should not be reused. Stop engine after 100 hours of running time and clean filter element , replace the fil- ter if necessary. Service air cleaner regularly accord- ing to Engine Operator’s Manual.

1.Locate the air filter canister located behind the engine door on the top of the engine.

2.Remove air filter element.

3.Remove loose dirt from element with compressed air or water hose directed from inside out.

Compressed Air: 100 psi maximum with nozzles at least one inch away from element.

Water Hose:

40 psi maximum without nozzle.

4.Soak element in a mild detergent solution for 15 minutes. Do not soak more than 24 hours. Swish element around in the solution to help remove dirt.

5.Rinse elements from inside out with a gentle stream of water (less than 40 psi) to remove all suds and dirt.

6.Dry element before reuse with warm air at less than 160o F (71o C). Do not use a light bulb to dry the ele- ment.
