the tool with a steady pressure, but do not use
excessive force as this will decrease the
efficiency of the tool. Start chipping with the
tool in a straight in position until the surface to
be broken is chipped. Draw the hammer back
at an angle of 60˚ with the surface to be
broken. Apply only enough force to keep the

"TOOL TIPS"
(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.
Avoid no load running of the tool. No load or
"empty blows" is the most damaging factor to
any impact hammer.
An electric 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.
