DeWalt D25901 Soft Start Feature, Active Vibration Control, Electronic Impact Energy Control fig

Page 9

ENGLISH

Soft Start Feature

The soft start feature allows the impact rate to build up more slowly, thus preventing the chisel or point from “bouncing” around on the masonry when starting up.

Active Vibration Control

The active vibration control neutralises rebound vibration from the hammer mechanism. Lowering hand and arm vibration, it allows more comfortable use for longer periods of time and extends the life of the unit.

Electronic Impact Energy Control (fig. 1)

The electronic impact energy control (c) offers the following advantages:

•use of smaller accessories without risk of breakage

•minimised break-out when chiselling soft or brittle materials

•optimal tool control for precise chiselling

Electrical Safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

Your DEWALT tool is double insulated in accordance with EN 60745; therefore no earth wire is required.

WARNING: 120 V units have to be operated via a fail-safe isolating transformer with an earth screen between the primary and secondary winding.

If the supply cord is damaged, it must be replaced by a specially prepared cord available through the DEWALT service organisation.

Mains Plug Replacement (Middle East and Africa)

If a new mains plug needs to be fitted:

•Safely dispose of the old plug.

•Connect the brown lead to the live terminal in the plug.

•Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the earth terminal.

Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 13 A.

Using an Extension Cable

If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see Technical Data). The minimum conductor size is 1 mm2; the maximum length is 30 m.

When using a cable reel, always unwind the cable completely.

ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set- ups or when making repairs. Be sure the trigger switch is in the OFF position. An accidental start-up can cause injury.

WARNING: Always wear gloves when changing accessories. The exposed metal parts on the tool and accessory may become extremly hot during operation.

Inserting and Removing SDS Max® Accessories (fig. 3, 4)

This machine uses SDS Max® chisels (refer to the inset in Figure 4 for a cross-section of a chisel shank).

Only DEWALT recommended accessories should be used with this product.

1. Clean the chisel shank.

WARNING: Do not apply lubricant to the machine.

2.Insert the chisel shank into the tool holder/ sleeve (e). Press and turn the chisel slightly until the sleeve snaps into position.

3.Pull on the chisel to check if it is properly locked. The hammering function requires the chisel to be able to move axially several centimetres when locked in the tool holder.

4.To remove a chisel, pull back the tool holder/ sleeve (e) and pull the chisel out of the tool holder.

Indexing the Chisel Position (fig. 5)

The chisel can be indexed and locked into 12 different positions.
