4. ASSEMBLY
4.1.
Refer to attached Parts List for numbers of components and their fixings.
4.2.
The crane must be installed and commissioned by qualified personnel. All relevant safety regulations must be strictly adhered to.
WARNING! For safety and ease of assembly, use two people to assemble the crane.
‰
IMPORTANT! DO NOT TIGHTEN ANY BOLTS UNTIL YOU ARE FULLY FINISHED WITH ASSEMBLY. OTHERWISE PARTS WILL
NOT LINE UP PROPERLY.
4.3.
Fit castors (23) to front (7) and rear (24) legs. Note: an additional pair of castors (23) (not supplied) can be fitted to the frame base (5)
where the main post tube crosses the frame.
4.4.
Slide the front legs (7) into front of the base (5)
4.5.
Slide rear legs (24) into the base (5).
4.6.
Use bolt (6) to secure legs (5 & 7) in position.
4.7.
Attach post (4) to the base. Do not tighten screw and leave a gap between the post and the base. This makes it easier to install the
supports (3) in the next step.
4.8.
Attach the supports (3) to the base and post. Then tighten all the bolts.
4.9.
Attach the boom (1) to the post.
4.10.
Attach the pump (18) to the post and boom (1).
4.11.
Attach the boom extension (2) to the boom (1).
4.12.
Fit chain and hook assembly (17).
4.13.
Tighten all bolts and nuts.
4.14.
Push the assembled crane into the working position, ensure that all the wheels touch the floor.
5. PREPARATION
p
5.1.
Purge air from hydraulic system
5.1.1.
Manual operating system:
(a) Make sure that the boom in its lowest position ( the piston of the pump is fully retracted into the cylinder)
(b) Turn release valve counterclockwise one full turn to the open position
(c) Quickly pump handle 10-20 full strokes to eliminate any air in the hydraulic system
(d) Turn release valve clockwise to the closed position.
5.1.2.
Carefully and slowly pinch oil fill plug to release trapped air.
5.2.
Check for proper pump action. It may be necessary to perform the above step (5.1.1 and 5.1.2) more than once to assume air is
completely evacuated.
6. OPERATION
. WARNING! Ensure that you read, understand and apply the safety instructions and warnings before use.
‰
WARNING! Ensure that you have familiarized yourself thoroughly with the product and the hazards associated with its improper use.

6.1.
RAISING THE CRANE
6.2.
Locate the hole on the Boom with a weight limit higher than the weight you will be lifting.
**For example: Locate the 1 TON hole on the Boom for a load that is under one Ton.
6.3.
Adjust the Boom Extension so the hole furthest from the hook-end aligns with the chosen hole on the Boom.
6.4.
Secure into place by inserting the Bolt through all aligned holes and tightening in place with the Washer and Nut.
6.5.
Move the Crane so that the Hook and Chain is directly above the item to be lifted.
6.6.
Securely attach the Hook and Chain to the item.
6.7.
To raise the Boom, turn the Jack's release valve fully clockwise (right). Insert the Handle into the Jack and pump (up and down)
repeatedly until the item has been lifted to the desired height.
6.8.
Be aware of the load weight, and check that it is within the capacity of the crane (at the jib extension you are using) and the sling or
support beam. When removing engines ensure you know the weight. Use only the lifting points recommended by the vehicle
manufacturer.
6.9.
Lift only from directly above the load. WARNING! DO NOT LIFT THE LOAD AT AN ANGLE!
6.10.
LOWERING THE CRANE
6.11.
Grasp the handle firmly with both hands. Securely hold on to the long ram handle so your hands do not slip and ensure the
release valve does not rapidly lower.
6.12.
Carefully open the Release Valve by slowly turning the handle counterclockwise. (Do not allow bystanders around the crane or
under the load when lowering the crane.
The crane is not a transportation device but may be used to reposition the load being worked on. To do so, lower load and jib
with care, to the lowest possible point before attempting to move. DO NOT try to move crane in a sideways direction. The crane is
not designed to support the load indefinitely. When you have repositioned the load, lower the load onto a secure and
appropriate working base, being fully aware of your own and other persons locations in relation to the lowering load.
6.13.
When load has been secured, remove lifting sling, support beam etc. and place crane in a safe location with lifting beam fully
lowered.
6.14.
After removing crane from the load, lower to lowest resting position to reduce exposure to rust and contamination.
7. MAINTENANCE
7.1.
Keep the crane clean and wipe off any oil or grease. Lubricate all moving parts.
7.2.
When not in use, the boom must be stored in the lowest position to minimize ram and piston corrosion.
7.3.
Before each use check all parts, ensure that all applicable bolts and nuts are firmly tightened. If any part of the crane is damaged or
suspect, remove it from service and take necessary action to repair.
7.4.
Periodically check the ram and piston for signs of corrosion. Clean exposed areas with a clean oiled cloth
7.5.
When crane efficiency drops, purge away air from the hydraulic system.
7.6.
Check the hydraulic oil level. If not adequate, add hydraulic oil as necessary. DO NOT use brake fluid or any other improper fluid.
7.7.
INSPECTION AND EXAMINATION OF CRANE BEFORE USE.
a)
Before each use of the crane, perform an inspection for leaks, damage, loose or missing parts.
