OPERATING INSTRUCTIONS
READ SAFETY RECOMMENDATIONS BEFORE
CONNECTING TOOL.
OPERATION
The Clecomatic Nutrunner is an automatic shutoff tool.
Accurate torque is achieved by setting the Clecomatic
clutch to the desired torque. The tool will automatically
shut off at this preset torque. Releasing the throttle lever
will allow the tool to reset for the next cycle.
The Rolling Impulse Nutrunner is designed to tighten
the fastener to a predetermined torque and "roll through"
at this torque.The throttle lever must be released to stop
the motor.
The Stall Nutrunner controls torque through the use of
a pressure regulator. Releasing the throttle stops the tool,
and the torque the operator counteracts will be dis-
charged.
CLUTCH ADJUSTMENT
The clutch is adjusted through the slot provided in the
clutch housing. The slot cover will have to be rotated to
expose the adjustment slot. Rotate the clutch until the
hole in the adjustment lock plate is visible. Insert a No. 1
Phillips screwdriver and rotate in a clockwise direction to
increase the torque setting or a counterclockwise direc-
tion to decrease the setting.
If the clutch is adjusted over the maximum power output
of the tool, the clutch will not function and the tool will
operate like a stall-type tool. Also, if the tool is being
operated at its upper torque limits, a drop in air pressure
could cause the clutch not to function due to a loss of
motor power and the tool will function like a stall-type tool.
If tool stalls operator must resist stall torque until he
releases throttle.
RIGHT ANGLE HEAD POSITIONING
Head positioning shims should be used to position the
right angle head in relation to the throttle lever so reaction
torque will not tend to retain the throttle lever in the "on"
position.
Operational check: Grip tool securely and be prepared
to counteract stall torque in case clutch is improperly
adjusted.
AIR SUPPLY
The tool is designed to operate at 90 psig (6.2 bar) air
pressure. The air pressure should be checked at the
tool's air inlet while the tool is running.
The use of an automatic in-line filter-regulator-lubricator
is highly recommended. This will supply the tool with
clean, lubricated air, keep it in sustained operation, and
increase tool life.
For maximum performance, use a 1/4" (6.5mm) I.D. air
hose up to 8 feet in length. If additional length is required,
a 3/8" (9.5mm) I.D. or larger hose should be connected
to the 1/4" (6.5mm) I.D. hose.
The air hose should be cleared of accumulated dirt and
moisture, then one-quarter (1/4) teaspoon (6.5mm) of
10W machine oil should be poured into the tool's air inlet
before connecting the hose to the tool.
LUBRICATION
The in-line lubricator should be checked regularly and
filled with a good grade of 10W machine oil. In the event
a line lubricator is not used, tools should be disconnected
from the air supply several times daily and several drops
of oil poured into the tool's inlet bushing.
Application of the tool should govern how frequently it is
greased. It is recommended that the idler gears receive
a generous amount of NLGI 2-EP grease after every 40
hours of operation. The clutch housing (left hand threads)
and clutch must be removed and the grease applied
through the hex in the spider. The right angle gears may
be greased through the grease fitting in the head.
