Bosch Gsh 16 Demolition Hammer Breaker Questions & Answers
Can a bad trigger cause my Bosch brute jackhammer not to run correctly
First to look for faultering contacts on electric field and carbon brushes sometimes a suppression capacitor can give some problems a worn commutator on the armature a switch can be overhauled with a direct cable contact to test to know if it is the switch test it out only with 2 persons for safety in that case.
Because my Bosch 11316EVS does not turn on

Control the power cable for wire breakage second remove the carbon brushes and control them on the collector surface for if there is a little black pin was coming out of it thats an auto protection build in then replace the brushes , but there are more things because there can be a problem with the electric field on a contact measure both coils and all the collectors (commutator around) on the armature that there is no-one lost the last option is the electronics
I have a bosch jackhammer 11388, motor runs fine but the bit not cutting
Position 856 1617000836 a broken hammer piston in the worst case but you have to order 1 617 000 A15 a maintence kit and special lubrication used 50 ml 1 615 437 512
INSPECT CAREFULLY THE 1 617 000 838 Hammer Pipe for rips if all parts are unmounted of the hammer pipe tap it with a metal object then it should not have any dull sound treat like a tuning fork for control for rips. thats important before repair consideration before.
The lubricant will be quite thick and that can also be the case only , (only have had its working hours on it) the revision of this hammers are easy to do it yourself clean solvent all metal parts that you re-use again to do the job you have a bench-vise and tools , for the striker pin in case there are no special tools neccesary like other hammers like a suggestion the Milwaukee 500S or other proffesional hammer because of the need of special seals and tools are neccesary , in between 1 and 2 hours are taken to service this Bosch hammers sometimes its neccesary to be aware of 1 ring to replace first of all because its easy to forget this ring on position 104 1610210095 o-ring that will very easy forgotten in practise with some grease replace it first of all spare parts.

What are the measurements of the connecting rod?
between all the collectors measure from the 2 the brusholders by slow turning around step by step the commutator and read at every step the resistance value, that should be on every step (almost) the same value if there is a gap on one step then replace the armature and in most case the associated drive sprocket because of in some cases a bad noise comming fromout the tool if the tool is much used.
Always measure the electric field that its also in balance. the values are depend on model (the wattage)
My bosch 11316evs pause during hammering
