EXTENSION CORD SELECTION

If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage drop which will cause loss of power and possible motor damage. A table of recommended extension cord sizes will be found in this section. This table is based on limiting line voltage drop to 5 volts (10 volts for 230 volts) at 150% of rated amperes.

If an extension cord is to be used outdoors it must be marked with the suffix W-A or W following the cord type designation. For example – SJTW-A to indicate it is acceptable for outdoor use.

FUNCTIONAL DESCRIPTION

FOREWORD

Porter-Cable Model 7765 Rotary Hammer can be used for impact drilling and for light chiseling work in masonry, using SDS or SDS-Plus style bits up to 7/8"diameter or SDS or SDS-Plus style chisels.

ASSEMBLY and OPERATION

START AND STOP THE MACHINE

1.CAUTION: Make sure switch is OFF and power circuit voltage is the same as that shown on the specification plate.

2.Connect machine to power circuit.

3.Grip machine firmly to resist starting torque.

4.Squeeze trigger switch (A) Fig. 1, to start motor. Release trigger to stop motor. As the trigger switch is squeezed the motor speed increases.

5.A lock button (B) Fig. 1, is provided to keep the motor running without holding the trigger switch ON. To lock the trigger switch ON, squeeze the trigger as far as it will go, push in lock button and release trigger.

To unlock lock button, squeeze trigger and release, leaving lock button free to spring out.

NOTE: The lock button can be engaged only when the machine is running at maximum speed.

CAUTION: Never use the lock button where machine may have to be stopped suddenly.
