INSTALLATION and MAINTENANCE INSTRUCTIONS

“K-21”DUAL HOSEREEL-DIRECTDRIVE

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-typesprings provide power for automatic hosetake-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.

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.

INSTALLATION

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

WARNING

Some reels with large or multiple springs are equipped with a ratcheted adjustment wrench. Follow separate instructions 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.

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

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

4.Connect free end of hoses to connections on machine.

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).

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.

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.

CAUTION

Do not exceed number of turns indicated on serial plate. Over-tensioningcan 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.

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 rubber mallet until shaft rotates freely and hub remains stationary.

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.

9. Tighten bolts securing spring housing to reel frame.

HOSE REMOVAL

Use the following procedure to remove worn or damaged hoses from reel prior to installation of new hoses.

1.Move machine serviced by reel to a position closest to reel. Spring will still be under pre-tensionat this point.

2.Turn off supply pressure to reel.

3.Disconnect hoses from machine or other attachments. Remove hose stops, if installed, and allow hoses to retract onto spool. Ensure all tension is off spring by manually rotating spool (normally clockwise when viewed from spring side).

4.Unwrap hoses without allowing spool to turn.

5.Disconnect hoses from elbows inside spool wrapper.

6.Install new hoses following directions below.

HOSE INSTALLATION

Use the following procedure to replace hoses or if reel was ordered without hoses. Refer to HOSE INSTALLATION REFERENCE DRAWING, below.

1.Unspool new hose from shipping spool and lay out to eliminate twist.

NOTE: This step is not essential, but will aid in winding operation of the reel and prolong hose life.

2.Connect hoses to elbows inside spool wrapper. (See drawing below.)

3.Wind the hose onto the reel spool by hand rotating spool in direction it turns free of spring tension. (Normally clockwise when viewed from spring side)

4.Complete working end connections.

5.Pretension reel and complete installation as described in REEL INSTALLATION section.
