PADDLE "ON/OFF" SWITCH

The paddle switch enables the operator to control the switch functions of "ON /OFF".

TO SWITCH THE TOOL "ON": Squeeze and hold the paddle lever. TO SWITCH THE TOOL "OFF ": Release pressure on the paddle lever. The switch is spring loaded and will return automatically.

INSTALLING ACCESSORIES

Clean the insert shank end of the accessory to remove any debris, then lightly grease with a light oil or lubricant. If work is to be done where the accessories are changed frequently and laid in dirt, sand or concrete dust, it is best not to grease the shank after wiping clean.

To lock standard air steel in place, lower the tool retainer lever all the way down and around the bottom and raise lever all the way up to the opposite side. To lock, insert air steel up to the striker and lower the retainer lever around the shank below the accessory collar as shown in figure 2.

To lock Bosch internal locking steel in place, lower tool retainer until you can slide the internal locking steel up to the striker. NOTE: notch on internal locking steel should always face toward the retainer lever. To lock, raise the tool retainer lever all the way up as shown in figure 3.

NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The "cost" to maintain sharp and undamaged accessories is more than offset by the "time saved" in operating the tool with sharp accessories.

REMOVING ACCESSORIES Accessories may be hot after use. Avoid contact

with skin and use proper protective gloves or cloth to remove.

To remove an accessory, reverse the previous directions. All accessories should be wiped clean after removing.

"TOOL TIPS"

The tool may be switched on with either hand. Balance the tool with both hands and rest the tool on the hip.

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. 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 weight on the accessory

All grease packed 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.

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.
