Machine Assembly
WARNING
To prevent serious injury, proper assembly of the
Drain Cleaner is required. The following proce-
dures should be followed:
Instructions For Mounting Handles and
Belt Guard
Handles – Assemble handles to machine frame and
secure with two (2) belt guard screws.
Belt Guard – Check the belt guard to ensure that it is
approximately 1/4 ″from the drum. Reposition guard if nec-
essary and tighten bolts (Figure 6) .
Gap between belt guard and drum
should not exceed 1/2 ″to prevent fingers being caught
between belt and pulley. Do not operate machine with-
out belt guard.
Instructions For Installing Cable
Do not remove bands or staples from cable
shipping carton. Cable is under tension and will whip
causing injury.

Machine Inspection
WARNING
To prevent serious injury, inspect your Drain
Cleaning Machine. The following inspection pro-
cedures should be performed before each use.
1. Make sure the Drain Cleaning Machine is unplugged
and the directional switch is set to the OFF position
(Figure 6) .
Figure 6 – K-750R Drain Cleaner
2. Make sure the foot switch is present and attached to
the Drain Cleaning Machine (Figure 6) . Do not oper-
ate the machine without a foot switch.
3. Inspect the power cord, Ground Fault Circuit Inter-
rupter (GFCI) and plug for damage. If the plug has
been modified, is missing the grounding prong or if the
cord is damaged, do not use the Drain Cleaning
Machine until the cord has been replaced.
4. Inspect the Drain Cleaning Machine for any broken,
missing, misaligned or binding parts as well as any
other conditions which may affect the safe and normal
operation of the machine. If any of these conditions are
present, do not use the Drain Cleaning Machine until
any problem has been repaired.
5. Lubricate the Drain Cleaning Machine, if necessary,
according to the Maintenance Instructions.
6. Use tools and accessories that are designed for your
drain cleaner and meet the needs of your application.
The correct tools and accessories allow you to do the
job successfully and safely. Accessories suitable for
use with other equipment may be hazardous when
used with this drain cleaner.
7. Clean any oil, grease or dirt from all equipment han-
dles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.
8. Inspect the cutting edges of your tools. If necessary,
have them sharpened or replaced prior to using the
Drain Cleaning Machine. Dull or damaged cutting
tools can lead to binding and cable breakage.
9. Inspect cables and couplings for wear and damage.
Cables should be replaced when they become severe-
ly worn or corroded. A worn cable can be identified
when the outside coils become flat.
Worn or damaged cables can break
causing serious injury.

WARNING
To prevent serious injury, proper set-up of the machine
and work area is required. The following procedures
should be followed to set-up the machine:
1. Check work area for:
