2.1  SAFETY ALERTS

Look for these symbols to point out 
important safety precautions. They 
mean:

Attention!   

Personal Safety Is Involved!

Become Alert! 

Obey The Message!

2.2  SIGNAL WORDS

The safety alert symbol is used in decals on the unit 
and with proper operation procedures in this manual. 
They alert you to the existence and relative degree of 
hazards. 

Understand the safety message. It contains important 
information about personal safety on or near the unit. 

2.3  NOTATIONS

NOTE:  General reference information for proper oper-
ation and maintenance practices.

IMPORTANT: Specific procedures or information 
required to prevent damage to unit or attachment.

2.4  PRACTICES AND LAWS

Practice usual and customary safe working 
precautions, for the benefit of yourself and others. 
Understand and follow all safety messages. Be alert to 
unsafe conditions and the possibility of minor, 
moderate, or serious injury or death. Learn applicable 
rules and laws in your area.

2.5  REQUIRED OPERATOR TRAINING

Original purchaser of this unit was instructed by the 
seller on safe and proper operation. If unit is to be used 
by someone other than original purchaser; loaned, 
rented or sold, ALWAYS provide this manual and any 
needed safety training before operation.

2.6  PREPARATION

Before starting any removal of parts, proper 
preparation is very important for efficient work. A clean 
work area at the start of each job will allow you to 
perform service repairs easily and quickly.

To reduce the incidence of misplaced tools or parts, 
place removed components with all attaching hardware 
in the disassembly order on a clean work surface. 
Organization is a key part of proper reassembly.

Tools, instruments, and parts needed for the job should 
be gathered before work is started. Interrupting a job to 
locate tools or parts is a needless delay. A list of 
required special tools has been included in this 
manual.

2.7  SERVICE POSITION

Place unit on a flat level surface. ALWAYS stop engine 
and disengage clutches. Tip up on the service bar for 
ease of access during some procedures. Assure unit is 
secure and will not tip over. Strap and clamp onto lift if 
used.

IMPORTANT: When unit is tipped up onto its service 
bar, undrained gasoline drawn into cylinder may wash 
cylinder wall and shorten engine life.

2.8  CLEANING AND STORAGE

IMPORTANT: Never spray unit with water or store unit 
outdoors to help prevent sealed bearing rust or 
corrosion. Water can seep into sealed bearings and 
reduce component life. Bearings are sealed against dirt 
and debris only.

A unit that is excessively dirty should be cleaned 
before work starts. Cleaning will occasionally uncover 
trouble sources. Dirt and abrasive dust reduce the 
efficient work life of parts and can lead to costly 
replacement.

When taking unit out of extended storage:

1. Check for any damage or loose parts. Repair, 

replace, or tighten hardware before operation.

2. If a preservative fluid was used in fuel tank, drain 

and discard. Fill fuel tank with fresh new fuel.

SECTION 2 - SAFETY

DANGER: IMMINENTLY HAZARDOUS 
SITUATION! If not avoided, WILL RESULT in 
death or serious injury. 

WARNING: POTENTIALLY HAZARDOUS 
SITUATION! If not avoided, COULD RESULT 
in death or serious injury. 

CAUTION: POTENTIALLY HAZARDOUS 
SITUATION! If not avoided, MAY RESULT in 
minor or moderate injury. It may also be used 
to alert against unsafe practices. 

CAUTION: Remove enough fuel so that no 
spillage will occur. Remove battery to prevent 
spillage of electrolyte. 

WARNING: AVOID SHARP EDGES which 
can cut. Movement of parts can cut off fingers 
or a hand. Wear gloves, and use extreme 
caution when servicing.
