Base Machine Assembly

The dust collector must not be connected to the power source

during assembly.

All instructions on this page refer to Figure 3.

Base and Base Extensions

1.Attach the base extensions (L) to the base (K) by inserting M8x20 hex head screws (A) through the mounting holes of the extension (L) and base (K).

2.Place M8 flat washers (D) and M8 lock washers

(G)on the ends of the screws (A) and fasten with M8 hex nuts (F), using 13mm wrenches.

Casters

1.The 3/8” hex nut (H) and M10 lock washer (J) are pre-assembled to each caster (M). For shipping purposes, the lock washer has been placed beneath the hex nut. Remove hex nut and lock washer from the caster shaft, re-install the hex nut, then install the lock washer above the hex nut, as shown.

2.Install the four casters (M) to the underside of the base (K) as follows:

3.Thread the caster shaft into the threaded hole on the underside of the base (K), turn until snug. Tighten the hex nut (H) against the base with a 14mm wrench.

Motor and Impeller Assembly

1.Place the base with casters down on the ground.

2.Attach the motor and impeller assembly (N) to the base (K) using six M8x20 hex cap screws (A), and six M10 flat washers (E). Hand tighten only until all screws and washers are in place, then tighten all six screws with a 13mm wrench.

3.Attach the inlet guard (O) to impeller housing (N) using eight M6x12 pan head flange screws (B).

4.Press the inlet port (P) onto the inlet guard (O) until it snaps into place. Secure in place with 3/16” x 1/2” pan head flange screw (C).

To reduce the risk of injury from moving parts, always keep inlet port (P) covered with the caps provided, if they are not connected to a hose.

Connector Tube and Switch Box

1.Place the lower gasket (Q) on the impeller housing (N). Line up the rubber pegs on the gasket (face down) with the holes in the housing.

2.Place the connector tube (R) on the impeller housing (N), making sure that the holes of the mating flanges are aligned.

Note: Refer to Figure 3 to make sure that the connector tube is facing the proper direction.

3.Insert an M8x20 hex cap screw (A), through the M8 washer (D) and flanges of the connector tube

(R) and impeller housing (N).

4.Place another washer (D) and a hex nut (F) on the protruding end of the screw (A) and hand- tighten only.

5.Mount the control box (S) to the two holes at the front of the connector tube flange (R).

6.Repeat steps 3 and 4 for the remaining screw locations, hand tightening only.

7.Tighten all hex nuts with a 13mm wrench.

Collector Housings

Mount the right collector housing (V) as follows:

1.Place an upper gasket (T) between the collector housing (V) and connector tube (R). Line up the pegs on the gasket (T) with the holes in the housing (V).

2.Place the collector housing (V) on the connector tube (R). Make sure to properly orient the collector housing – the internal baffle must slope downwards toward the center.

3.Insert a screw (A) through the washer (D), connector tube flange (R), and collector-housing flange (V).

4.Place another washer (D) and a hex nut (F) on the protruding end of the screw (A) and hand- tighten.

5.Repeat steps 1 through 4 for the seven remaining screw locations.

6.Tighten all screws and hex nuts with a 13mm wrench.

7.Repeat steps 1 through 6 for the left collector housing (U).

Support Bars

1.Align the bottom slots of a support bar (W) with the holes in the base (K). Insert two screws (A) with two flat washers (D) and hand tighten only.

Note: If you are using the Canister Filter System, proceed with steps 2 through 5 below. If you are using the Filter Bag System, leave the support bar (W) as is, for further assembly later, and proceed to “Handles”.

2.Align the top holes of the support bar (W) with the holes at the rear of the collector housing (V) and insert two screws (A) and two flat washers

(D).

3.Place a washer (D) and a hex nut (F) on the protruding end of each screw (A) inside the collector housing, and hand-tighten only.

4.Adjust the lower part of the support bar (W) as needed using its slots, until it is straight. Then tighten all four screws on the support bar (W).

5.Repeat for the other support bar.
