OPERATION
Instructions for Use (Fig. A, D)

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of injury, turn
appliance off and disconnect appliance from power
source before installing and removing accessories,
before adjusting or changing set-ups or when
making repairs. An accidental start-up can cause injury.
1. Plug the power cord into an appropriate outlet.
2. Turn the on/off/tool control switch
15
to the ON
position ( ).
3. Set the variable suction dial
14
to the desired position.
This feature allows the user to control the vacuum's power,
suction and noise.
NOTE: This setting also controls the level of suction. This
is very useful in applications where the vacuum creates
unacceptable levels of drag to the work piece.
4. Follow the direction under Connecting to Power Tools to
connect to the power tool to be used.
Flow Alarm Adjustment (Fig. D)
Class M models only
Adjust the flow alarm adjustment control
16
to the correct
hose (or tube) inside diameter size or accessory diameter
referring to the largest section. The chosen diameter of the
adjustment control must be equal or bigger as the largest
diameter of the used hose/tube/ accessories. The hose supplied
is 32mm inside diameter. An acoustic alarm will sound if the
flow rate falls below 20 m/s. The system has a time delay to
reduce unintended alarms.
If the alarm sounds when there is no apparent blockage:
1. Ensure that the adjustment control is set to the correct
diameter.
2. If the flow rate adjustment is set below the maximum,
increase this level until sufficient flow through the hose
causes the alarm to stop.
3. If the alarm still continues to sound, remove hose and check
that it is clear. Remove and replace dust bag if full or blocked
and check filter condition and replace where necessary.
If the alarm continues to sound contact your local
DeWALT
service agent.
