SAFETY MEASURES DURING MAINTENANCE
3-24
SUPPORTING THE BOOM
When work needs to be conducted under a raised boom then
the boom must be supported against the danger of suddenly
falling. For this purpose you should use either a jack stand,
which should be positioned below the boom, or a support device
(1) which is mounted over the piston rod.
The support device is available as an optional extra.
Order No: 42T-98-12050
When using the support device the following procedure must be
adhered to at all times.
1. Park the machine on a piece of level, solid ground.
2. Put the parking brake on.
3. Place the wheel chock in front of the wheels to prevent the
machine from rolling away.
4. Lift the boom up sufficiently far so that the supporting device
(1) can be installed over the lifting ram's piston rod.
5. Switch the engine off.
6. Position the supporting device (1) over the piston rod without
standing under the boom and tighten the bolt (2) by hand.
7. With the engine off, lower the boom slowly until it rests on
the support device (1).
8. Set the drive direction selector to "N" and move the working
hydraulic's catch lever to position "1".
