35STH

2. Product Description

The pulse nutsetter features
- torque shut-off,
- push-to-start with soft-start valve,
- has a lockable torque adjustment accessible from the outside
- reversible, RH and LH operation,
- generates less than 77 dB(A) when idling and at clockwise
rotation
- generates less than 2,5 m/s² vibration when pulsing
- Optional shut-off signal for connection to electronic verifier

3. Torque and Speed Adjustment

Disconnect air hose before adjustment!
- For square drive models hold the hydraulic rotor <81> from turning
by using a SW 13 (A/F 1/2") wrench. With Quick Change version
pull sleeve <105>.
- For torque adjustment first turn adjusting screw< 95> counter-
clockwise until the stop is reached for minimum torque.
- Turn the adjusting screw clockwise approx. 0-4 full turns to adjust
the tool to required torque range 10-35 Nm (7,4 - 26 lbf.ft).
- For further tuning of torque speed adjust air throttle <30>, clockwise
to reduced speed, counterclockwise to increase speed.

4. Inspection and Maintenance

Regular inspection is essential in order to prevent breakdowns, high
repair costs and long downtimes associated with the pulse nutsetter.
Always follow and use the safety notes P1687S and this type-specific
operating manual for maintenance and inspection tasks
Example for torque setting
1. Bolt M8 = 25Nm
2. Set torque screw by 2,3 turns
3. Free speed 3400 ¹/min
4. Set exhaust throttle to 70° clockwise

The inspection and maintenance list below contains timings, checks
and maintenance tasks to be carried out when the pulse nutsetter has
completed 100, 250 and 500 hours of operation
Operating time = number of rundowns x tightening time
Example: Predicative tasks (250 hours of operation) are to be
carried out at an effective tightening time of, for instance, 1.8
seconds after 500000 rundowns
Preventative tasks after 100 hours of operation
- Inspect suspension for operational reliability
- Inspect drive for wear
- Inspect air supply for firm connection
- Inspect free speed
Predicative tasks after 250 hours of operation
Replacement of (refer to operating manual)
- Oil out of the pulse unit
- Hydraulic service kit
- Motor service kit
General overhaul after 500 hours of operation
Inspection of component parts and replacement as necessary of
- Suspension
- Trigger valve
- Exhaust air throttle
- Motor unit
- Pulse unit
