Pre-operation Inspection
WARNING
Before each use, inspect your threading machine
and correct any problems to reduce the risk of seri-
ous injury from electric shock, crushing and other
causes and prevent threading machine damage.
1. Make sure that the threading machine is unplugged
and the REV/OFF/FOR (2/0/1) Switch is in OFF (0)
position.
2. Clean any oil, grease or dirt from the threading
machine, including the handles and controls. This
aids inspection and helps prevent the machine or
control from slipping from your grip. Clean and main-
tain the machine per the
Maintenance Instructions
.
3. Inspect the threading machines for the following:
• Inspect the cords and plugs for damage or modifi-
cation.
• Proper assembly, maintenance and completeness.
• Any broken, worn, missing, misaligned or binding
parts or other damage.
• Presence and operation of the foot switch. Confirm
that foot switch is attached, in good condition, that it
cycles smoothly and does not stick.
• Presence and readability of the warning labels
(See Figure 1 & 2)
.
• Condition of the dies, cutter wheel and reamer cut-
ting edges. Dull or damaged cutting tools increase
required force, produce poor results and increase
the risk of injury.
• Any other condition which may prevent safe and
normal operation.
If any problems are found, do not use the threading
machine until the problems have been repaired.
4. Inspect and maintain any other equipment being
used per its instructions to make sure it is functioning
properly.

Selection of appropriate materials and instal-
lation, joining and forming methods is the responsibility of
the system designer and/or installer. Selection of improp-
er materials and methods could cause system failure.
Stainless steel and other corrosion resistant materials can
be contaminated during installation, joining and forming.
This contamination could cause corrosion and premature
failure. Careful evaluation of materials and methods for the
specific service conditions, including chemical and tem-
perature, should be completed before any installation is
attempted.
Machine Assembly
WARNING
To reduce the risk of serious injury during use, fol-
low these procedures for proper assembly.
Failure to mount the threading machine to a stable
stand or bench may result in tipping and serious
injury.
ReV/oFF/FoR Switch should be oFF and machine
unplugged before assembly.
use proper lifting techniques. RIdGId 535 threading
machines weigh 260 lbs. (118 kg) or more.
Mounting on Stands
The Threading Machines can be mounted on various
RIDGID Threader Stands.
Refer to RIDGID catalog for
stand information and to the respective Stand Instruction
Sheet for mounting instructions
.
Mounting on Bench
The machines can be mounted on a level, stable bench. To
mount the unit on a bench, use four 5/16"-18 UNC bolts in
holes provided at each corner of the machine base. Base
hole spacing is 29.5" x 15.5" (749 mm x 394 mm). Tighten
