CV-SERIES — PREPARATION AND OPERATION

Before using your Vibrator Motor, read and fully understand all of the safety and operating instructions not only for the motor, but also for the flexible shafting and the head that will be used with the motor.

1.The vibrator motor, flexible shafting, and heads are shipped from the factory ready to use. Connect per instruction bulletins.

2.Use only the combination of flexible shafting and heads shown below in Table 3.

Table 3. Shaft Sizes

MODEL	SHAFT	HEAD SIZE	MAX. SHAFT
			LENGTH
SVA-1	314V	900	21 FT.
		1000
		1300
		1400	28 FT.
SVA-2	382V	1700
		2100	21 FT.
		1400
SVA-3	382V	1700	35 FT.
		2100
		2600

3.To connect the 314V or 382V flexible shafting to the vibrator motor see illustration (Figure 4).

WARNING

MAKE CERTAIN the motor is disconnected from the power source and the switch is in the "OFF" position.

4.Slide the core out of the casing far enough to thread the spindle (Item 3 Fig. 4) into the core fitting and tighten. A pair of pliers and a wrench can be used to tighten the connection. It is important that this connection is tight. If it is not, the torque of the motor plus the load of the head will jam the two fittings together making it extremely hard to loosen them for disassembly.

5.Thread the shaft coupling (Item 2 Fig. 4) into the casing ferrule and tighten.

6.Pull up on the lock pin and slide the shaft assembly into the front motor bearing housing and release the lock pin. Give the shaft assembly a twist to make sure that the lock pin is seated in the lock groove of the shaft coupling.

7.Clean the mating parts threads with Locquic Primer "T". Allow to dry several minutes before applying a ring of Loctite No. 271 or equivalent to the middle of the casing threads. Screw the head tightly to the casing and wait 1 hour before using. Threads are left-hand; turn counter-clockwiseto tighten.

CAUTION

If the shaft begins to helix (buckle) excessively during operation, stop and investigate. This is an indication of an overload condition.

CAUTION

The vibrator head is cooled by the concrete. Operation of the vibrator head in air longer than 2 minutes at a time will cause overheating of the bearings which will result in premature head failure.

CAUTION

Visually inspect the air intake and exhaust frequently to make sure the motor has sufficient air for cooling.
