ELECTRICAL SAFETY

switch on the equipment before operating. The purpose of this switch is to shut down the power.

■

NEVER use a extension cord that is frayed or damaged where the insulation has been cut.

■

NEVER carry the equipment by its power cord or disconnect it by yanking the cord from the power outlet.

■

ALWAYS make certain that the proper extension cord has been selected for the job. See Extension Cord Gauge Selection Table.

sure the receptacle circuit is connected to either a GFCI receptacle or a receptacle protected by a 20 amp circuit breaker.

■

When plugging the unit into a power receptacle, check the nameplate for the correct operating voltage. Operating the rebar bender at the wrong voltage will damage the electrical components. ALWAYS read the nameplate before applying power.

■

This unit is equipped with a 3-prong male power plug. DO NOT use a 2-prong adapter when plugging into a wall outlet. This will defeat the purpose of the ground circuit. If the plug does not fit into the receptacle, contact a qualified electrician to install a 3-conductor wall receptacle (outlet).

■

Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is grounded.

■

DO NOT expose the hydraulic power unit to rain or wet conditions. Water entering the power unit will increase the risk of electrical shock.

■

When operating the unit outdoors, be sure to use the appropriate outdoor extension cord. This type of extension cord reduces the risk of electrical shock.

■

ALWAYS remove the AC power cord from the power source before performing any service or maintenance on the unit. This preventative safety measure reduces the possibility of accidental starting.



When operating near an arc welder, it is important the both the unit and the welding equipment be connected to the same earth ground. If they are not, server damage to the unit, particularly to the power cord could occur. Personal injury may also occur.

4. When using a roller with a bearing, bearing must face downward.

5. When using a collar with a bearing, bearing must face downward.

6. To prevent the roller and the collar from coming off, attach the washer securely with the bolt.

7. Position the stopper so that rebar to be bent is parallel to the front of the stopper and tighten the rebar securely in place. If the rebar is not parallel to the front, the bending angle will be incorrect. See Figure 3.
