1. Safety instructions
Regarding name plates, warning labels and labels:
・Never remove or deface any name plates, warning labels or labels which are
attached to the body.
The operator should always observe them.
Regarding installation (page 8):
・Take sufficient care not to knock or drop the reel when handling.
Never use the arm of the guide roller (special accessories) to lift the reel.
Regarding hose connection (page 9):
・Fluid leakage hazard.
Stop supplying the fluid to the hose reel before the work.
・Do not install hose to drum over winding length plus dead turn (2-3 turns).
Make free space in drum, otherwise hose could spill out from drum cover.
If hose spilled, it causes accidents as a hose cutting.
・When used for vertical lift or horizontal stretch application, in order to prevent
severing of the hose and then a fall in case of a spring breakage, protect the hose
by wrapping rubber or the like around the hose portion which contacts with the
oblong hole in the drum cover.
・Connect hose securely to prevent the fluid leakage from connected part.
Regarding initial tension setting (page 12):
・Never let go of the drum during any work.
When released, the drum suddenly rotates, possibly causing personal injury.
・After setting the initial tension, hose connection requires more than 2 people to
secure the drum and connect the hose.

・Use within the rated values of maximum working pressure (1.5 MPa {15kgf/cm
2
}).
・Never pull out the hose past the winding length.
Always leave 2 - 3 dead turns on the drum. (To the sign of red tape)
Put sign (red tape) on the 2 - 3 dead turns when installing or replacing the hose.
Regarding periodic inspections (page 16):
・Periodically inspect the reel and replace any worn or damaged parts.
Carefully check the hose has no damage.
・If a malfunction is found during a periodic inspection, never reuse the reel but
repair immediately.
・Allow the hose to fully wind onto the drum to give the minimum winding tension
before carrying out inspections.
・Fluid leakage hazard.
Stop supplying the fluid to the hose reel before carrying out any work.
・Always put up instruction signs ("Equipment being inspected", "Do not open the
valve", etc.) before carrying out periodic inspections or repair.
・Always use genuine parts for replacement.
・Test the fluid leakage on the hose and reel after the reel has been stored for a long
time.

5. Hose Connection
5-1. Calculation of required hose length on winding side
Figure 9
Hose length on winding side = Winding length + Extension length + Connection length
+ Dead turn length + Connection length inside reel.
Winding length = The length wound onto the drum.
Extension length = The length from the hose's fixed point to the end of the winding,
which is not wound onto the drum.
Connection length = The length required to connect the mating equipment to the hose's fixed point.
Dead turn length = The length of the 2-3 dead turns.
Required dead turn length = (Drum diameter + Hose diameter) × π×2 ~ 3
Number of dead turns
The length of 1 drum turn
5-2. Hose connection
・Fluid leakage hazard.
Stop supplying the fluid to the hose reel before the work.
・Do not install hose to drum over winding length plus dead
turn (2-3 turns).
Make free space in drum, otherwise hose could spill out
from drum cover.
If hose spilled, it causes accidents as a hose cutting.
・When used for vertical lift or horizontal stretch
application, in order to prevent severing of the hose and
then a fall in case of a
spring breakage, protect the hose by wrapping rubber or
the like around the hose portion which contacts with the oblong hole (F) in the
drum cover (Refer to Figure 10).
・Connect hose securely to prevent the fluid leakage from connected part.

6. Spring Tension Adjustment
6-1. Relationship between winding torque and drum turns
Figure 14
Number of initial
spring turns
means the number of spring turns which provides the initial tension
required for winding the hose onto the drum.
Number of spare
spring turns
means the number of remaining spring turns when the hose is fully paid out.
A shortage of spare spring turns shortens the spring life and causes spring
breakage.

Upper limit of initial spring turns = Total number of spring turns
- (Number of drum turns + Number of spare spring turns)
Example) Model HR-6855W for the case of 12 drum turns
According to Table 1, Total number of spring turns = 24.
According to Table 2, Standard value of initial spring turns = 2 - 6
Number of spare spring turns = 3 or more
Upper limit of initial spring turns = 24 - (12 + 3) = 9
Then the allowable number of initial spring turns = 2 - 9
6-3. Initial tension setting
・Never let go of the drum during any work.
When released, the drum suddenly rotates, possibly causing personal injury.
・After setting the initial tension, hose connection requires more than
2 people to
secure the drum and connect the hose.
(1) Wind the whole hose around the drum before connecting to the mating equipment.
NOTE: Take care not to twist the hose around the drum.
(2) With the hose still wrapped around the drum, rotate the drum by hand in the payout direction the same
number of turns as “standard value of initial spring turns” (Refer to Table 2).
This becomes "initial spring turn".
(3) Without letting the drum rotate, unwind the hose to the connection length plus the extension length
and connect the hose to the mating equipment.
Check there are no twists in the hose before connection.
(4) Pull out the hose to the winding length, then let the hose wind around the drum.
Ensure the drum can recover the hose full length.
(5) If the drum stops during recovery, the initial spring tension is insufficient.
Disconnect the hose from the mating equipment and increase the number of initial spring turns in the
same manner.
NOTE: Set the initial tension as small as possible and never exceed the upper limit of the initial spring
turns.
Over - tensioning could cause a spring breakage.

7. Measure against Uneven Winding
Uneven
winding
means the hose is wound on mainly one side of the drum width.
The uneven winding will cause the hose to drop from the drum or recovery problems,
resulting in damage to the hose.
7-1. Checks before adjustments
(1) Check the reel position is correct.
Refer to Section 4-2. "Installation" (page 8).
Adjust the X and Y axes of the reel.
(2) Check there are no twists in the winding side hose.
If the hose is twisted, disconnect the hose from the mating equipment and
remove any twists.
※If uneven winding still exists after the above checks, adjust according to
the next section.
7-2. Adjustments
(1) Initial tension modification.
Increase the number of initial spring turns one by one without exceeding the upper limit.
If there is no improvement, set the initial tension back to the first value.
(2) X axis modification.
Tilt the X axis at a small angle by inserting a spacer under the bracket.
Figure 15
(3) Y axis modification
Tilt the Y axis at a small angle after adjusting the X axis.

8. Safety Instructions on Use
・Never approach the moving parts during operation.
There is a danger of being caught up.
・Before supplying different fluid into the hose, take maker's advise.
If there is no specification request on the type of fluid application, the product
will be for air, water (less than 80ºC), lubricating oil (Mineral type),
grease (lithium type).
If you are applying different kinds of fluid from standard fluid type,take
maker's advise.
・Shut off the fluid supply immediately in case of any trouble to avoid the
problem
escalating.
・Never use the reel when damaged or abnormal sound/vibration occurs.
・Never alter the reel or its accessories.
・Never let go of or unfasten the hose from the fixed points when the hose is
pulled
out.
The hose will rewind suddenly, possibly causing personal injury.
・Use within the rated value of maximum working pressure (1.5Mpa {15kgf/cm2}).
・Never pull out the hose past the winding length.
Always leave 2-3 dead turns on the drum. (To the sign of red tape)
Put sign (red tape) on the 2-3 dead turns when installing or replacing the hose.

・Never employ a swivel base or a standard turn table for side attachment or
inverse attachment.
(1) Turn table
This can swivel the reel up to 300゜(Refer to Figure 18).
When turned, take care the fixed side hose is not put under excessive
force or contacts the reel or surrounding objects.
An arm type guide roller or pipe type guide roller is required together
with the turn table.
Please contact our company in case of side attachment, the
specifications differ from the standard ones.
(2) Arm type guide roller (Refer to Figure 19)
This is required when the reeling direction angle varies during
operation.
Attach the arm to the spindle and fix with the hexagon socket head cap
screw.
(3) Pipe type guide roller
This is required when the reeling direction angle
varies during operation.
For installation, attach the pipe ends to the sides of
the base plate.
The pipes cannot be attached in case of reverse
seating.
(4) Stopper (Attached to the hose)
This will stop the hose at the attached location during
a winding operation when used with the arm type
guide roller or pipe type guide roller.
(5) Ratchet device (Use for pulling the hose manually)
This is used when the winding operation stops and
the hose is still paid out.
To stop the drum, pull out the hose slightly then let it return.
To release the drum, pull out the hose so as to rotate the drum by 1/2 turn.
