Mast Assembly
Reference should be made to the illustrations which follow the text.
1. Before commencement of assembly examine the items and ensure that there are no missing or
damaged parts. The following items of equipment will be required (not Abacus supply);
•
Telescopic handler or similar to erect the base (typically 0.5 tonne)
•
Torque wrench suitable for 310Nm on the HL250 and 850Nm on the HL330.
•
Timber supports and packers
2. The holding down bolts are each fitted with two nuts and washers. The upper nuts and washers
and template should be removed. The threads should be examined for any damage and rectified
using a die nut if necessary. The nuts should be set in a level plane using a steel bar and spirit
level across each opposing pair of nuts. Check, referring to the counterbalance operating
instructions (see section 3.6), that the base section is fully closed and locked. Using a tele-handler,
lift the mast base and place over the foundation bolts and on to the lower set of nuts, ensuring the
direction of lowering is as required and that the mast will clear any obstructions.
