UL 62841-3-12-2019 pdf free download.Electric Motor-Operated Hand-Held Tools, Transportable Tools And Lawn And Garden Machinery — Safety — Part 3-12: Particular Requirements For Transportable Threading Machines.
7 Classification
This clause of Part 1 is applicable.
8 Marking and instructions
This clause of Part 1 is applicabte. except as follows:
8.1 Addition:
– maximum diameter of the thread which can be created. The maximum diameter may be specified in SI units or inches.
NOTE According lo the International System ot Units, oy SI Unds arc to be used Neveriheless, some pipe diameters and Ihreads are still speofied in inches internationally.
8.14.1 Addition:
The additional safety instructions as specified in 814.1.101 shall be given. This part may be printed
separately from the “General Power Tool Safety Wamings.
8.14.1.101 Threading machine safety warnings
a) Keep floor dry and free of slippery materials such as oil, Slippery floors invite accidents.
b) Restrict access or barricade the area from bystanders when the workpiece extends beyond the machine to provide a minimum of one metre clearance from the workpiece. Restricting access or barricading the work area around the workpiece will reduce the risk of entanglement.
C) Do not wear gloves. Gloves may be entangled by the rotating pipe or machine pails leading to personal injuiy.
d) Do not use the machine for other purposes such as drilling holes or turning winches. Other uses or modifying this machine for other applications may increase the risk of serious injuiy.
e) Secure the machine to a bench or stand. Support long heavy pipe with pipe supports. This practice will prevent the machine from tipping.
f) While operating the machine, stand on the side where the operator control switch is located. Operating the machine from this side eliminates need to reach over the machine.
g) Keep hands away from rotating pipe and fittings. Stop the machine before wiping pipe threads or screwing on fittings. Allow the machine to come to a complete stop before touching the pipe. This practice will reduce the risk of entanglement in rotating pans.
h) Do not use this machine to install or remove fittings. This practice could lead to trapping.
entanglement and loss of control.
NOTE Repiicing nsIalI 01 removes with “make 01 bieak” is possible
I) Do not operate the machine without all covers properly installed. Exposing moving parts increases the probability of entanglement.
j) Do not use this machine if the foot switch is broken or missing. The foot switch provides safe control of the machine. such as emergency shutoff in case of entanglement.
8.14.2 b) Additional items:
101) Instruction on the proper location of the operator while operating the machine:
102) For threading machines with multiple gear box settings: information about which gear box setting is to be used for each thread diameter and style.
9 Protection against access to live parts
This clause of Part I is appliCable.
10 Starting
This clause of Part 1 is applicable.
11 Input and current
This clause of Part 1 is applicable, except as follows:
