Operating The Machine; Checking The Fuel Supply; Starting The Engine - Komatsu WB140-2N Operation & Maintenance Manual

OPERATING THE MACHINE

Before starting your work operations it is important to perform several procedures to be sure your equipment is safe to operate.
It is also important to be aware of the hazards involved when operating your machine. Study the section in safety: See "PRE-
CAUTIONS BEFORE STARTING WORK OPERATIONS" on page 1-8 before proceeding with any work operations.

CHECKING THE FUEL SUPPLY

Before starting the machine it is important to be sure there is enough
fuel in the fuel tank. To check, turn the ignition key to the "ON" position
and read the fuel gauge (1).
If fuel is low, add fuel. Be sure when filling the fuel tank you leave
enough space in the tank for the fuel to expand. Never overfill the fuel
tank.
Do not smoke when refueling and do not use fuel additives or mix gaso-
line with diesel fuel. these may damage fuel pump and injector parts.

STARTING THE ENGINE

Before starting the engine be sure all personnel are clear of your work
area or travel path. To start the engine:
Be sure the directional control lever (1) is in a neutral (N) position. The
engine will not start with the directional control lever in a forward or
reverse position.
Be sure the throttle control lever is set at a low idle speed.
With your foot off the accelerator pedal turn the ignition key to the start
position.
When the engine starts, release the key, the ignition switch will return to
the "I" position automatically
With the engine now running, check all the gauges and warning indica-
tors. Be sure the system is operating normal and you allow the engine
and hydraulic system time to warm up before starting work.
Remark
If the engine does not start within 15 seconds, release the
ignition switch and wait for 30 seconds before trying again. If
it will not start, do not continue to crank the engine, damage
to the starter may result. Contact your Komatsu Dealer for
repairs.
