PNEUMATIC INSTRUCTION SHEETS
P1 - Replace Hand Control & Airline Tubing - Air Leak Test
IMPORTANT
NOTE: If an air leak is suspected, it is important to check the entire pneumatic
system for air leaks. There are NO serviceable parts inside the pneumatic Hand Control.
1.
Separate the Airline tubing from the black grommet on the hoist unit.
2.
Take note of the force required to separate these items. The connection should be very tight.
If the connection appears somewhat loose, an air leak may develop and cause a problem.
3.
Test for air leaks in each Button separately, by depressing a button.
4.
Hold the Hand Control and place a finger over the end of airline tubing.
5.
Release the depressed button. If button stays in the depressed position, there are no air
leaks in the button. If button rises slowly after a few seconds, an air leak MAY be present.
Repeat a couple of times to ensure that the end of the airline tubing is completely covered.
6.
Repeat Steps 2 to 4 for each button in turn.
7.
Air leaks occur at the grommet connections because the hand control and airline tubing are
frequently used to pull the hoist along the track. This results in the frequent disconnection of
the airline and grommet.
8.
Remember to reassemble the airline to the black grommet by aligning the ribs. If not
connected correctly, operating buttons on the hand control will not function properly.
