Note. The belt should push down no more than 13mm.
To select a faster drill speed, move the belt up to a higher
step on the front and central pulleys and lower step on the
central and rear pulleys. Rotating the pulleys and “rolling”
the belt onto the larger pulley will make this easier.
To select a slower drill speed, move the belt down to a
smaller step on the front and central pulleys and a higher
step on the central and rear
pulleys. Rotating the pulleys and
“rolling” the belt onto the larger
pulley will make this easier.
To tighten the belts on
the pulleys pull the motor
backwards. This is best done by
grabbing hold of the top of the
rear pulley and the bottom of the
motor housing.
Rotate the pulley by hand to
ensure everything is aligned
and correct.
Tighten the belt tension
lock knob.
Replace the pulley cover.
