Chapter 7 - Prestart Inspection; Operator's Manual; Engine; Oil Level - Snorkel TB42J Operato's Manual

Potential service and safety problems may be detected
by inspecting the aerial platform. This chapter includes
information on properly inspecting the aerial platform and
includes a prestart inspection check list at the end of the
chapter to ensure that no areas are overlooked.
A
Warning
The potential for an accident increases when oper-
ating an aerial platform that is damaged or mal-
functioning. Death or serious injury can result from
such accidents. Do not operate the aerial platform
if it is damaged or malfunctioning.
Perform a prestart inspection at the beginning of each
shift, before using the aerial platform on the job. The in-
spection site must have a smooth and level surface.

Operator's Manual

The manual holder is located in the engine compartment
(refer to Figure 7.1) on the left side of the machine. Make
certain it is securely fastened in place.

Check to see that the proper Operator's Manual is in the
holder. The manual should be complete with all pages
intact and in readable condition.

Engine

Open the engine compartment doors on both sides of the
machine and visually inspect the engine and its compo-
nents with the engine off.

Oil Level

Check the engine oil level before starting the engine so
the oil has drained to the pan. The proper oil level is be-
tween the add and full marks on the dipstick.
The distance between the top and bottom dipstick marks
corresponds to about 1 quart US (1 l). Add oil, if neces-
sary, before starting the engine.

Coolant
Cummins engines are liquid cooled. When the engine is
cold, there should be about 1" (2.5 cm) of coolant in the
bottom of the reservoir (refer to Figure 7.1).
A
Caution
Engine coolant escaping under pressure can cause
serious burns. Shut the engine off and let it cool
before removing the radiator cap.
Add coolant, if necessary, when the engine is cold and
not running. When running at operating temperature the
coolant should be at the hot level.
Deutz engines are air cooled. Visually inspect the air
intake and fan (refer to Figure 7.2) to be sure they are
free of obstructions that could stop or slow the flow of air.
Inspect the fan belt to see that it is in place and not
cracked.

Radiator

Inspect the radiator hoses and clamps for wear, leakage,
or damage (refer to Figure 7.3). Make sure the hoses are
not hardened, cracked, or feel spongy. Make sure the
cap is in place and tight.
