Bosch HS2126 Breaker Hammer, 1-1/8" Shank, Tent Stake Driver Questions & Answers
Breaker Hammers size question
After considering the application work, determine the carrier on which the breaker will be installed. Gorilla Hammers has assigned a 'Recommended Carrier Weight' range to each breaker. If the operating weight of the carrier falls within this range, the carrier will safely handle this model of breaker. If the desired breaker falls outside of this recommended carrier weight range, the carriers lifting capacity and oil flow will need to be verified to ensure a proper fit.
Lifting Capacity: Provided the weight of the breaker does not exceed the maximum lifting capacity at any position, the carrier is assumed to be stable. On most loader backhoes and excavators, the maximum lifting capacity is lowest when the boom is at full reach. This is the value that must be compared to the operating weight of the breaker.
Oil Flow and Operating Pressure: A required oil flow range is specified for each breaker. Oil flow to the breaker within this range is adequate for operation. However, for maximum productivity the carrier should be capable of providing the maximum required flow. Compare the maximum oil flow requirement of the breaker with the oil flow capacity of the carrier. Remember the breaker operates at 1500-2500-psi. therefore, oil flow should be evaluated at operating pressure.
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
COld be the powercable (think on the electric field by the sliding contacts) or a to short carbon brush or a broken ring on the impact bold in front inside , pauze can be mechanical or electric.
I just need to disassemble to regrease and
NO WAY if it had its operating hours you should know that the most parts are worn and by leaking in the front of the hammer tube all the o-rings and seals will burn in a very short time in between hours or weeks.
Allways look for the right wear and tear part kits for your model and that has also the right lubrication for it.
