Maintenance - Milwaukee M18 ONEFHIWF1 Operator's Manual

Using the Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow the
motor to come to a complete stop before using the
control switch.
Push for
Forward
PUSH TO CENTRE TO LOCK
1. For forward (clockwise) rotation, push the control
switch in the direction shown. Check the direction
of rotation before use.
2. For reverse (counterclockwise) rotation, push the
control switch in the direction shown. Check the
direction of rotation before use.
3. To lock the trigger, push the control switch to the
centre position. The trigger will not work when the
control switch is in the locked position.
Always remove the battery pack before performing
maintenance or changing accessories. Always
lock the trigger or remove the battery pack before
storing the tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
These tools may be operated at any speed from 0
to full speed.
1. To start the tool, pull the trigger.
NOTE: An LED is turned on when the trigger is pulled.
2. To vary the driving speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed.
3. To stop the tool, release the trigger.
Impacting Techniques
The longer a bolt, screw, or nut is impacted, the
tighter it will become. To help prevent damaging the
fasteners or workpieces, avoid excessive impact-
ing. Be particularly careful when impacting smaller
fasteners because they require less impacting to
reach optimum torque.
Practice with various fasteners, noting the length of
time required to reach the desired torque. Check the
tightness with a hand-torque wrench. If the fasteners
are too tight, reduce the impacting time. If they are
not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under the
head of the fastener affects the degree of tightness.
The torque required to loosen a fastener averages
75% to 80% of the tightening torque, depending on
the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a
relatively light torque and use a hand torque wrench
