BA-SERIES TROWEL— SAFETY MESSAGE ALERT SYMBOLS

FOR YOUR SAFETY AND THE SAFETY OF OTHERS!

Safety precautions should be followed at all times when operating
this equipment. Failure to read and understand the Safety
Messages and Operating Instructions could result in injury to
yourself and others.

HAZARD SYMBOLS

NOTE

This Owner's Manual has been developed to provide
complete instructions for the safe and efficient operation
of the MultiQuip BA-SERIES WALK-BEHIND TROWEL.
For engine maintenance information, please refer to the
engine manufacturers instructions for data relative to its
safe operation.

Before using this WALK-BEHIND TROWEL, ensure
that the operating individual has read and
understands all instructions in this manual.

SAFETY MESSAGE ALERT SYMBOLS

The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,

WARNING, or CAUTION.

Lethal Exhaust Gases

Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and

odorless, and can cause death if inhaled.

Explosive Fuel

Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited. DO
NOT start the engine near spilled fuel or
combustible fluids. DO NOT fill the fuel tank

while the engine is running or hot. DO NOT
overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or
sparks from the ignition system. Store fuel in
approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.

DANGER: You WILL be KILLED or

SERIOUSLY injured if you DO NOT follow
directions.
