Side Handle (Fig. 1)
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the
side handle properly installed and securely tightened. Failure to do so may result in the
side handle slipping during tool operation and subsequent loss of control. Hold tool
with both hands to maximize control.
The side handle (c) can be mounted in front or in rear position on either side of the
machine to suit both RH- and LH-users.
WARNING: Always operate the tool with the side handle properly assembled.
