Refer to Fig. 22 for the components of Grip assembly.
(1) Remove Retaining ring (INT) R-15 with 1R291.
(2) Remove M8x65 Hex bolt from Pole complete by turning
the bolt counterclockwise.
(3) Remove Arm R complete from Arm L.
(4) Remove Arm L from Pole complete by turning the arm
clockwise.
Note: Grip assembly for DHP481 has M5x10 Thumb screw
and M5 Hex nut, and therefore, the grip is different
from that of DDF481. Loosening the thumb screw
will cause the M5 Hex nut to be removed from Arm L.
Be careful about the loss of the M5 Hex nut when
DHP481 is disassembled.
(1) Screw Pole complete in Arm L to the full.
(2) Insert the rod of Arm complete R into the hole of Arm L. (Fig. 23)
(3) Connect the male thread of M8x65 Hex bolt with the female thread of Pole complete as drawn in Fig. 24.
(4) Set Retaining ring (INT) R-15 in place of Arm R complete.

Hole of Arm L Rod of Arm R complete
Five to six turns of the thread of M8x65 Hex bolt must be
connected with Pole complete before DDF481/ DHP481

Note: • Be sure to route the lead wires for LED circuit to the space between ribs of Gear assembly after setting
Gear assembly in place. (Fig. 20)
If the routing is done before assembling Gear assembly, the breakage or pinching of the lead wires will happen.
• When Housing L are fastened to Housing R, the clearance is left because of the existence of Gear assembly in
Housing L and Housing R. Therefore, clamp them with a waterpump pliers carefully. (Fig. 21.)
