300 Compact Pipe and Bolt Threading Machine
Clean metal shavings and other debris from the chip
tray of the Threading Machine. Check the level and
quality of the thread cutting oil. Replace or add oil if
necessary. Reservoir in the base will hold approxi-
mately five (5) quarts of thread cutting oil.
NOTE! If using 250 Folding Stand, be sure to remove
oil seal pressure plate.
NOTE! Thread cutting oil lubricates and cools the threads
during the threading operation. A dirty or poor
grade cutting oil can result in poor thread quality.
NOTE! To drain dirty oil and properly maintain the oil sys-
tem, refer to the "Maintenance Instructions".
Machine and Work Area Set-Up
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. Locate a work area that has the following:
• Adequate lighting
• No flammable liquids, vapors or dust that may
ignite.
• Grounded electrical outlet
• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
• Dry place for machine and operator. Do not use
the machine while standing in water.
• Level ground
2. Clean up the work area prior to setting up any equip-
ment. Always wipe up any oil that may have splashed
or dripped from the machine to prevent slips and
falls.
3. If the workpiece extends more than four (4) feet be -
yond the Threading Machine, use one or more pipe
stands to prevent tipping and the oscillation of the
pipe.
4. If the workpiece extends beyond the Threading Ma -
chine, set-up guards or barricades to create a min -
imum of three (3) feet of clearance around the Thread -
ing Machine and workpiece. This "safety zone" pre-
vents others from accidentally contacting the machine
6
or workpiece and either causing the equipment to tip or
becoming entangled in the rotating parts.
5. If necessary, fill the reservoir with RIDGID Thread
Cutting Oil.
6. Make sure FOR/OFF/REV switch is in the OFF posi-
tion.
7. Position the foot switch so that the operator can
safely control the machine, tools and workpiece. It
should allow the operator to do the following:
• Stand facing the directional switch.
• Use the foot switch with his left foot.
• Have convenient access to the directional switch,
tools and chucks without reaching across the
machine.
Machine is designed for one person operation.
8. Plug the Threading Machine into the electrical outlet
making sure to position the power cord along the
clear path selected earlier. If the power cord does not
reach the outlet, use an extension cord in good con-
dition.
WARNING
To avoid electrical shock and electrical fires,
never use an extension cord that is damaged or
does not meet the following requirements:
•The cord has a three-prong plug similar to
shown in Electrical Safety section.
•The cord is rated as "W" or "W-A" if being used
outdoors.
•The cord has sufficient wire thickness (14 AWG
below 25'/12 AWG 25'-50'). If the wire thickness
is too small, the cord may overheat, melting
the cord's insulation or causing nearby objects
to ignite.
To reduce risk of electrical shock, keep all
WARNING
electrical connections dry and off the ground. Do not
touch plug with wet hands.
9. Check the Threading Machine to insure it is operat-
ing properly.
• Flip the directional switch to FOR (Forward). Press
and release the foot switch. Check that the Thread -
ing Machine rotates in a counterclockwise direction
as you are facing the front chuck. Have the Thread -
ing Machine serviced if it rotates in the wrong direc-
tion or if the foot switch does not control its stopping
or starting.
