PAGE 44
Instruction Manual - RIV938 O-ring part number 4371800 CAUSE SOLUTION No traction. Tool needs oil. When inserting the rivet nut in the tie rod, after pressing the trigger, tool does not unscrew properly. Not enough oil in tool. Check the O-ring (B) and replace it. O-ring part number 4371800 When you have to work on the pressure switch: 1. Remove air 2. Loosen the oil cap (27) to avoid the coming out out of gasket (C). In case of replacement use guide (1).
PAGE 45
Instruction Manual - RIV938 CAUSE SOLUTION Air leaks from muffler (T). Check the two O-rings (O4) and o-ring (21 part number 3235600) which could be worn or broken. Motor screwing When the rotating pin (6 part number 4151500) is broken and you replace it, the motor may rotate continuously, which means that the shaft (13 part number 3761300) is too long; in this case it will have to be shortened by a few tenths to obtain the closure of the ball (14 part number 3096900).
