Section 2 - Operation Refueling Procedure

2.11 Refueling Procedure

This section provides the operator with the procedure
on how to refuel the engine with regular fuel and install
the propane cylinder.

IMPORTANT

Before using the aerial platform ensure

there is enough fuel to finish the job.

WARNING

Follow all local and national regulations

for propane handling.

WARNING

Failure to heed the following safety
precautions could result in death or
serious injury:

Use extreme caution while refueling •
aerial platforms.

Ensure engine and all systems are •
turned off before refueling.

Refuel aerial platform only in a well •
ventilated area away from open
flame and other sources of ignition,
authorized by your employer and
supervisor.

Liquid propane gas fuel is a gas •
that is heavier than air. It settles in
low spots. Any flame or spark could
cause a fire that could cause serious
injury.

When changing liquid propane gas •
cylinder, check all connections for
damage or missing parts. Never try
to start an aerial platform if you smell
gas.

2.11-1 Regular Fuel

Ensure engine and all systems are turned off and 1.
emergency stop buttons are depressed.

Open fuel compartment door and remove fuel 2.

Carefully pour fuel into tank ensuring that no 3.
spillage occurs.

Securely replace fuel cap.4.

Ensure there are no leaks in the fuel system.5.

Wipe up any spilled fuel.6.

Dispose of rags in an approved container.7.

Protection of Environment from Chemical
Dangers

WARNING

Gasoline, diesel fuel, engine oil and
hydraulic fluid are chemicals, which can
contaminate the environment. If they
are spilled during filling and reach the
water, they can cause damage to the
environment, e.g., death of fish. For
such damage, the party responsible is
liable! Therefore, gasoline, diesel fuel,
engine oil or hydraulic fluid must not get
into the sewage system, streams, rivers
or other surface water. For that reason,
immediately remove the dripped off or
spilled gasoline, diesel fuel, engine oil
or hydraulic fluid with appropriate means
and dispose of these means according to

the regulations.

For gasoline engine models, use only •
unleaded gasoline with an octane
rating 87 or higher.

WARNING

Do not smoke in an area where aerial

platforms are stored or refueled.

Section 2 - Operation Winching and Towing Procedure

2.13 Winching and Towing Procedure

This section provides the operator with procedure about
winching and towing and on how to manually release
brakes.

WARNING

Ensure boom is in stowed position before
winching or towing. Sudden motion could
cause aerial platform to become unstable.

Death or serious injury could result.

WARNING

In emergency situations where aerial
platform functions are not available and
lowering is impeded by an obstacle,
utmost care must be taken to move
ae rial platfo rm far enough to clear
obstacle. In such cases, operation must
be extremely smooth with no sudden
movements and must not exceed a speed

of 2 in./sec (50 mm/sec).

WARNING

When pushing, winching or towing, do

not exceed 2 mph (3.2 km/h).

4. Position aerial platform on a firm and level
surface.

5. Chock or block wheels to prevent aerial platform
from rolling.

6. Apply brakes by pulling out black brake auto reset
valve.

NOTE

Brakes automatically apply when platform

controls are engaged.

WARNING

Brakes must be applied immediately after

reaching desired location.

WARNING

Do not winch or tow aerial platform on

grade steeper than 45% (4WD).

WARNING

Do not winch or tow aerial platform onto a
slope, or brake the towing vehicle rapidly.
Do not pull aerial platform down an incline

towards a winch.

1. Before winching or towing aerial platform, fully
retract, lower and position boom over rear drive
wheels in line with direction of travel.

2. M an u a l l y r e l e a s e b r a k e s ( r e f e r t o

The LCP or OUP that an individual surface can withstand varies from structure to structure and is generally determined by the engineer or
architect for that particular structure.

OUP

LCP – Locally Concentrated Pressure – is a measure of how hard the aerial platform tire tread presses on the area in direct contact with the
floor. The floor covering (tile, carpet, etc.) must be able to withstand more than the indicated values above.
OUP – Overall Uniform Pressure – is a measure of the average load the aerial platform imparts on the whole surface projected directly
