ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle)

the side grip so that the teeth on the grip fit in between the
protrusions (A) on the tool barrel. Then tighten the grip by
turning clockwise at the desired position. It may be swung
360° so as to be secured at any position.
To remove the side grip, loosen it by turning counterclock-
wise. Then push the grip base away from the tool barrel to
disengage it from the protrusions (B).
