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

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.
AVOID SHARP EDGES which
Never spray unit with water or store unit
