1.2.2 Removing the 979 from the Skid
There are two methods for removing the 979 from the skid. Both methods require two
people. The second method involves removing the
Skid-Mates (the blue donut-shaped
mounts at the front of the skid) from the skid.
WARNING
Handle the leak detector carefully and properly in the following
steps. Personal injury or damage to the leak detector could
result from improper handling. The 979 is heavy and can cause
personal injury if not handled carefully when removing it from
the skid.
Method 1
1. With the assistance of a helper, carefully roll the leak detector toward the front of the
skid.
2. Lift the front end of the unit and gently lower it onto the floor.
3. Lift the rear of the unit and roll it on the front casters until it is clear of the skid.
4. Gently lower the rear end onto the floor.
Method 2
1. Using the brace removed in Step 6 of Section 1.2.1 “Unpacking Instructions” as a lever,
carefully raise the front edge of the skid between 1" and 2".
2. While a helper holds the leak detector against the back brace, unscrew and remove the
front two Skid-Mates by turning them in a counterclockwise direction.
3. Make sure the helper is still holding the leak detector against the back of the skid, then
gently lower the front of the skid to the floor.
4. Carefully and slowly roll the leak detector off the skid and onto the floor.
1.2.3 Removing Loose Packing
Once the 979 is off the skid, take out and remove all loose packing from the leak detector.
