INTRODUCTIONANDINSTRUCTIONS
The CAV 26 comes fully assembled. It is specifically designed for dry pick-up of fine dust made from grindings of wood
or gypsum. It is mounted on tough rubber wheels, two of which swivel in order to make the machine easy to handle. It
also has brakes to safely stop the machine in place.
NOTE: When performance has declined noticeably, empty tank and clean the filters accordingly.

Features
Figure 1, 1 - Control Panel
For explanation of controls, see "Controls" section this page.
Figure 1, 2 - Inlet
This inlet is for installation of vacuum hose and accessories.
Figure 1, 3 and Figure 2, 1 - Debris Canister
The debris canister should be emptied when the canister is full.
To empty canister, lift debris canister lever (figure 3,2). Debris
canister will lower until it rests with it's wheels on the floor. Grip
the handle and remove the canister, then empty it's contents.
To fit the canister back in place, set it under the vacuum, making
sure the full sight level gauge (figure 3,1) remains visible from the
outside. Then push lever (figure 3,2) downwards, allowing the
canister to lift until it fits against filtering chamber.
Figure 1, 4 - Filter Cleaning Lever
This lever is to used to clean the filter. When manometer (figure
4, 1) reads that the filter is clogged, turn the filter cleaning lever
several times with force in order to shake the dust from the filter.
Do not operate lever with vacuum running.
Wait a few minutes for the dust to settle at the bottom of the
container, then empty.
Figure 3, 1 - Full Sight Level Gauge
This gauge indicates the debris level in the debris canister (figure
1,3). The debris canister should be emptied when it is full.
Before emptying debris canister, switch off the machine by
pressing the vacuum motor switches (figure 4,2) and remove
plug from the power supply.
Figure 3, 2 - Debris Canister Lever
Lift this lever so that debris canister can be removed and emp-
tied. Make sure to lower the lever when you replace the debris
canister.
Figure 3, 3 - Balancing Hose
Balances vacuum around polytank liner (fig 2,2), so it's not
sucked into the filter.
Controls
Figure 4, 1 - Manometer to display filter loading
The vacuum in the filter increases proportionally as the filter
clogs. Then the manometer needle will move from green (filter
good) to the red (filter clogged) section.
Figure 4, 2 - Vacuum Motor Switches
This model is fitted with 3 motors, so it has three vacuum motor
switches on the control panel. Press the switches to start the
vacuum motors. The warning lights (green lights) will come on.
Press the switches again to stop the motors. The warning light
will go out.
Figure 4, 3 - Electrical Label
Figure 4, 4 - Illuminated Mains Voltage Indicator
When on, this indicates that the vacuum is connected to the
electrical supply.

OPERATINGINSTRUCTIONS
To operatethismachine followthese procedures:
1. Position the CAV 26 in a convenient location near
awalloutlet andwithin reachof the workingarea.
If the surface is not level, set the brakes on the
casters.
CAUTION: Do not use an extension cord with
the CAV 26 or you will experience a loss in
performance. Should an extension cord be
necessary, use one sized 12 AWG and no
longer than 50' in length. An extension cord
sized smaller than 12 AWG or greater than 50'
in length will overheat and potentially cause a
fire.
2. Connect the CAV 26 to a wall outlet matching one
of the two shown in figure 5. No adaptor should be
used with this appliance.
WARNING: This appliance must be grounded.
Should an electrical malfunction occur, the
grounding conductors provide a path to
harmful current. Do not connect this
appliance to any other wall outlet than one of
those shown in figure 5. Consult an
electrician if there is reason to doubt that the
wall outlet is not wired correctly. Do not
remove the grounding pin on the power cord.
Do not use this appliance with a damaged
power cord or plug.
3. TheCAV26 usesthree individuallyactivated
vacuummotors thatallowtailoringthe deliveryfor
theavailable electricalsupply andapplication.
ForLight DutyApplications:
Activateone ofthe threevacuums. Toactivate a
vacuummotor, pushone ofthethree vacuummotor
switches(see figure6). Todeactivatethevacuum
motor, push the vacuum switch a second time.
ForHeavy DutyApplicationsor Multiple
SimultaneousUsers:
Activatetwo ofthe vacuummotors ifyou are
connected to a 15Awall outlet. You may activate
all three vacuum motors if you are connected to a
20Awall outlet.
WARNING: Do not activate all three vacuum
motors if you are connected to a 15A wall
outlet or you will overload the circuit. An
overloaded circuit will overheat and
potentially cause a fire. Always deactivate the
vacuum motor(s) before disconnecting the
power cord.

the lever (fig. 7, 3) as shown.. The poly-liner
providesquick convenientdisposal.
5. When the debris canister becomes full, the
manometer (fig. 8, 1) reads in the red,
deactivatingall vacuummotors.
6. Allow time for the dust to settle, then operate the
filtercleaning lever(fig. 9,1) severaltimes.
7. Removethe poly-linerandreplace witha new
liner.
8. Replace the debris canister. To fit the canister
