the air tube (6) from the regulator (2) to the Servo (1). You should hear air
bleeding at the Servo.
10. Turn the adjustment ring on the Servo clockwise until the load starts to rise.
11. Turn the adjustment ring counter-clockwise until the load is balanced.
12. Tighten set screw on pilot regulator screw and Servo to maintain adjustment.
Servo Installation On Wire Rope
1. Mount unit on overhead suspension.
2. Position Servo below travel range of the wire rope.
3. Insert wire rope through top hole in the Servo. Install 2 clamps on wire rope
38 mm (1-1/2 in.) above top of Servo and 38 mm (1-1/2 in.) apart. Leave 406
mm (16 in.) of wire rope free for Servo to operate properly.
4. Insert wire rope through bottom hole in the Servo. Install 2 clamps on wire
rope 38 mm (1-1/2 in.) apart.
5. Install load hook.
• You must leave enough slack in the wire rope to allow proper operation of
the Servo unit.
Servo Installation On Chain
1. Mount unit on overhead suspension.
2. Position Servo below travel range of the chain.
3. Attach chain to U-Bolt and Servo. Do not cut chain at this time.
4. Count 25 links of chain 400 mm (15-3/4 in.).
5. Attach 26th link to bottom U-Bolt and Servo.
6. Measure length of chain needed below Servo to determine chain length.
7. Cut chain to desired length.
8. Connect chain to load hook.
The regulator is the primary control for the S Control system. The Servo bleeds off air. Therefore it works like
an amplifier. If the pilot regulator must be readjusted for any
reason, the auxiliary flow, trim valve and Servo must be readjusted.
(E) Control Basic Unit
(E) Regulator Installation Refer to Dwg. MHP1356
Place the unit on a clean, sturdy work surface with the end cap
upright. Pull out the wire rope or chain until reel bottoms out.
Remove E control kit from package. Check to ensure that "O" Ring
is in the port on the back of the regulator (1). Install the regulator
on the end cap with the 4 mounting screws and lock washers (2, 3,
4). Connect control hose to port A on regulator and the port on the
control handle.
Operational Adjustments
• Prior to performing operational adjustments make sure air
supply is off.
• The unit may not support the weight of the empty handling
device, or may raise device at a potentially hazardous rate.
Extreme care must be used until control adjustments are
complete.
