2.Setup/Operation

*DANGER! It is very important that you read and understand this section before operating the

hose reel! Failure to follow the procedures and cautions in this manual could lead to injury or

possible death! *

The Hose Reel has a master power switch, a motor direction switch, a belt tension switch, a motor

speed dial, and a circuit breaker. These controls can all be found on the Control Panel (seen below in

Figure 2-1).

*CAUTION! When NOT operating the reel, put the reel Main Power Switch toggle switch in the "Off"

position to prevent accidental activation and possible injury. When the hose reel is to be left

unsupervised, the power cord should be unplugged from the

power supply. *

Power is present when the MAIN POWER switch is in the

"ON" position. The motor is operated by depressing the foot

switch, which operates a momentary contact (will only

operate when depressed).

Mode 1 – Powered Load

Mode 2 – Freewheeling Unload

Mode 3 – Powered Unload

Mode 4 – Cold Starting

*CAUTION! Take care not to allow your hands, feet or

clothing to become trapped in any of the reel's moving mechanisms. *

Mode 1 – Powered Load

The LOAD mode is achieved by the mode toggle switch is in the LOAD position and the

belt is sufficiently tightened to transmit power from the motor/gearbox to the hose reel

spool.

The foot switch is momentary and will only operate when it is depressed.

The hose must be directed manually into position on the hose reel.

The hose reel speed may be varied by means of the MOTOR SPEED dial.

Mode 2 – Freewheel Unload

The BELT TENSION switch controls the linear actuator which positions the pivot arm, on

the end of which is an idler sheave that depresses the drive belt. This adjusts the belt

tension. With the belt loosened the hose reel may freewheel.

It is important to maintain sufficient tension on the belt to allow a degree of braking on the

hose reel spool while unrolling hose. The hose reel spool possesses a variable amount of

inertia depending on its mass and its angular velocity. This necessitates gradually loosening

the belt as the hose is unloaded: less spool inertia (from decreased mass) requires less

braking.
