5. If needed, place protective covers in the
work area. The drain cleaning process
can be messy.
6. Place the Drain Cleaning Machine on
the ground with the drill shaft vertical.
Machine should sit squarely and firmly
on the ground. Do not operate with the
drill shaft horizontal. This will reduce the
risk of tipping.
7. Remove the battery from the drill (see
Specifications). Securely attach the drill
chuck to the hex of the drill shaft (Figure
4). Set the battery powered drill torque
adjustment to the maximum setting (do
not place in the "drill" setting). Set the drill
speed in the 1800 to 2500 RPM range,
and place the direction selector in the
FORWARD (FOR) position (see direction
marking on the front housing).

8. Position the Drain Cleaning Machine so
that the cable outlet is within 3' (1 m) of
the drain access. Greater distances from
the drain access increases the risk of
the cable assembly twisting or kinking. If
the FlexShaft Machine cannot be placed
with the cable outlet within 3' (1 m) of the
drain access, extend the drain access
with similar sized pipe and fittings (see
Figure 5). Improper cable assembly sup-
port can allow the cable to kink and twist
and can damage the cable or injure the
operator. Extending the drain back to the
Drain Cleaning Machine also makes it
easier to feed cable assembly into drain.

9. Disconnect the chain knocker from the
hook and pull approximately 4' (1.2 m) of
cable assembly out of the machine.
10. Mark the sheath to indicate when the
chain knocker is approaching the drain
opening when withdrawn. This can be
done with tape. This reduces the risk of
the chain knockers coming out of the
drain and whipping around. The distance
depends on the configuration of the drain,
but should be at least 4' (1.2 m) from the
chain knocker.
11. Ensure chain knocker is properly installed
(see Installing/Adjusting Chain Knocker).
12. Insert chain knocker end at least 1' (0.3 m)
into drain.
13. Evaluate the work area and determine if
any barriers are needed to keep bystand-
ers away from the drain cleaning ma-
chine and work area. The drain cleaning
process can be messy, and bystanders
can distract the operator.
14. Position the machine for easy accessibil-
ity. You must be able to hold and control
the cable assembly and the drill switch.
15. With dry hands, insert the battery into
the drill.
