For the best penetration rates in concrete,
run the tool with a steady pressure, but do
not use excessive force as this will decrease
the efficiency of the tool.
All hammers require a short period of time to
warm up. Depending on the room
temperature, this time may vary from
approximately 15 seconds (90˚F) to 2
minutes (32˚F). A new hammer requires a
break-in period before full performance is
realized. This period may require up to 5
hours of operation.
A combination hammer is likely to be the
most expensive portable tool at the
construction job. The long wear and efficient
operation of the BOSCH hammers will more
than justify the cost for tools of this type. As
earlier pointed out, sharp accessories as well
as clean air vents are necessary for efficient
operation. Establish and follow a set
maintenance program.
