INSTALLATION and MAINTENANCE INSTRUCTIONS

UH18 UNIVERSAL HOSE REEL-DIRECT DRIVE

☞ NOTE: These instructions are written for machine pull reels.

If installing or servicing hand pull reel, use only those steps marked with hand ☞ .

All units are provided with right hand rotation unless otherwise specified. This means that hose is pulled off spool top left or bottom right (spool rotates clockwise to wind hose) when

viewing spring end of reel. See diagram on parts page.

Clock-type springs provide power for automatic hose take-up.

Spring must be pretensioned at time of installation to

insure that tension is applied to hose at all times. A tension adjustment spanner wrench is provided with each reel.

INSTALLATION

WARNING

If machine pull reel, move machinery to position closest

to reel before adjusting spring tension. Adjusting tension with hose extended may result in

damage to reel or personal injury.

1. Install hose if reel was purchased without hose. See instructions on page 4.

2. Insure that machinery to be serviced by reel is at position closest to reel.

☞ 2. Securely mount reel in desired position using 1/2"(M12). Be sure spool is aligned with hose run.

☞ 3. Position hose guide if supplied so hose pays-out as straight as possible through hose guide.

☞ 4. Connect free end of hose to connections on machine or adjust hose stop so that desired length of hose extends from reel.

☞ 5. Connect flexible supply lines to swivel fitting. See HOSE INSTALLATION REFERENCE DRAWING.

NOTE: Do not hard plumb to swivel fitting.

☞ 6. Remove cover plate on spring housing to expose shaft and spring hub. (See Figure 1).

☞7. Insert spanner wrench into holes in spring hub (Fig 2). Rotate spanner wrench counter-clockwise. Number of 360˚ turns should match last digit in model number on serial plate.

WARNING

Some reels with large or multiple springs are equipped with a ratcheted adjustment wrench. Follow separate instruc- tions for its use. Failure to use ratcheted wrench, on reels so equipped, could result in serious personal injury.

MAINTENANCE

Periodically: A. Inspect hose

for wear and check mounting

bolts and other hardware for

tightness.

B. Check for broken springs

by pulling about 2/3 hose off

reel and observing “Broken

Spring Indicators” on sides of spring canisters (Fig. 3).

NOTE: Bearings and springs are prelubricated and require no periodic maintenance.

WARNING

Do not attempt to remove spring from its housing. Clock- type springs can be dangerous to handle. Removal of spring from housing could result in personal injury.

SPRING REPLACEMENT

The unique SAFETYCHANGE® spring motor consists of a spring and hub sealed within a housing. A replacement spring is supplied sealed in its housing and the old unit should be discarded completely.

☞ 1.	Turn off supply pressure to reel.
2. Insure that machinery to be serviced by reel is at
	position closest to reel. Disconnect hose from
	machine connections.
☞ 3.	Wind all hose onto reel to relieve all spring tension.

☞ 4.	Remove inspection cover from face of spring housing.
☞ 5.	Rotate spool clockwise and observe inner shaft.
	Shaft should rotate clockwise and hub (with
	spring attached) should remain stationary.

NOTE: Do not attempt to remove spring if resistance is met or hub tends to rotate with shaft. Continue to rotate spool and strike end of shaft several sharp blows with a lead hammer or rubber mallet until shaft rotates freely

and hub remains stationary.

CAUTION

Do not exceed number of turns indicated on serial plate. Over-tensioning can cause a broken spring, sheared shaft or other damage.

WARNING

Do not attempt to relieve spring tension using spanner

wrench. Doing so may result in personal injury.

☞6. Remove (4) bolts which secure spring motor to frame.

☞7. Slide spring motor off shaft and discard.

☞8. Install replacement spring motor, pawls and pawl springs.

NOTE: Pawl springs must be located between the pawls

and the deepest section of the shaft grooves.

Make sure that pawls and pawl springs are inserted flush

with ends of shaft and hub or they may rub against

inspection cover. See Fig 4, page 4.
