Safety Instructions; Assembly And Operation - Mega CRV6 Instrucciones De Uso Y Mantenimiento

R
EXTREMELY IMPORTANT
Read these safety instructions carefully in addition to the instructions for use, operation and maintenance. Keep them in a safe
place for later consultation. This crane has been designed for use as a hoist with extensive use in industry and garages, particularly
in the handling of engines. Any other application beyond the conditions established for use of this crane will be considered
inappropriate.
Handle the crane correctly and ensure that all parts and components are in good condition and that no parts are missing. Take
special care with the elevation accessories used with the crane, such as slings, supports, compensators etc.
The crane should only be used by authorised persons, having read carefully and understood the contents of this manual. Do not
modify the crane in any way. Non-compliance with these instructions may result in injury or damage to the user, the crane or the
load to be lifted.
The manufacturer accepts no responsibility for the improper use of the crane.

1. SAFETY INSTRUCTIONS

1.1 The load to be lifted should never exceed the rated capacity of the crane in each of the positions of the hoisting arm.
1.2 Ensure the element to be lifted against any type of slipping. Do not apply any lateral pressure to the elevated or suspended
load.
1.3 The crane should be supported on a solid, level and horizontal, non-slip surface. It should be well illuminated and free of
unnecessary obstacles.
1.4 Both children and unauthorised persons should be kept away from the work area.
1.5 Prior to proceeding to work with the crane, make sure that the slide is perfectly fitted to the limiting axle (Fig.T). The crane
arm should be located in the nearest possible position to the load to be elevated. Make sure that there are no elements in the
vicinity which hinder the elevation of the load or obstacles which prevent its lowering. When securing the load to the hook,
always use appropriate elevation elements with a capacity superior to that of the load to be elevated. Check that the safety
trigger functions correctly.
1.6 To lift the load in a stable and balanced way, suspend it from the hook and bear in mind that its centre of gravity should always
be within the crane support base (Fig.V).
1.7 Never allow the load to sway or lower it brusquely as this may prove to be dangerous.
1.8 Do not place any part of the body under the elevated load (Fig.X), and do not climb on top of the crane.
1.9 The crane is not a transportation element but in the event that it is necessary to move the load a short distance, position the
arm of the crane in the lowest possible position. Once the movement has been completed, place the load on the ground. The
crane is not a device to maintain the load elevated for an unlimited period of time.
1.10 As a safety measure against overload, the crane is fitted with an overload valve, set at its maximum working pressure at the
factory. This valve should not be tampered with under any circumstances.
1.11 To lower the load, turn the knob (Fig.Y). This system enables the lowering to be regulated and controlled manually and
precisely. As another safety element, the crane is fitted with an LCS system to avoid brusque lowering, resulting from a possible
incorrect manoeuvre. The crane will stop the lowering process when the knob is not activated (Fig. Y)

2. ASSEMBLY AND OPERATION

As we are handling heavy elements, it is essential to carry out the following assembly processes with the help of other people.
2.1 Break the box and assemble the wheel brackets on the column (Page2/ Fig. 1-2).
2.2 Lift the crane and attach the hydraulic unit to the arm using the provided axle. Make sure that the rings are correctly placed
(Page2/ Fig.3).
2.3 To assemble the legs, place the crane on the ground and introduce the rivet and the screw in the position indicated (Page2-3/
Fig.4-9).
2.4 By last, place auxiliar wheel bracket with the provided axles and rings (Page3/ Fig.10).*Only necesary in CRP10 y CRP20
models.
2.5 Prior to using the crane, the hydraulic circuit needs to be drained in order to eliminate any air from the valve system of the
hydraulic unit. Turn the hydraulic group knob 90º (Fig. Y) while pumping the lever several times. By releasing the knob the crane
is ready for use. Turn the hydraulic unit to work in the most confortable position.
2.6 To lift the load, activate the lever. If lifting an engine, secure it at the points recommended by the manufacturer.
2.7 When the use of the crane is completed, the piston of the hydraulic unit should be fully retracted. First move the slide to its
initial position.
3. MAINTENANCE
Important. Both the maintenance and repair of this crane may only be carried out by qualified and authorized personnel, who as a
result of their training and experience are familiar with the hydraulic systems used in these devices.
3.1 Clean and lubricate the axes of the moving parts of the crane at regular intervals (Fig. Z).
3.2 Only original spare parts should be used.
3.3 Withdraw the crane from service if it is suspected that it has been subjeted to abnormal loads or has suffered any type of knock
until the problem has been resolved.
3.4 If the oil level needs to be checked or refilled, dismantle the hydraulic unit and with piston fully retracted, remove the filler
plug and drain its contents into a container. With the hydraulic unit in a horizontal position, proceed to introduce the necessary
volume for each model as indicated. Avoid the entrance of any dirt with the new oil.
Important. An excess of oil over the volume required may affect the operation of the crane.
3.5 Only use hydraulic oil, HL or HM type, with a maximum ISO grade of cinematic viscosity of 30 cSt at 40º, or of an Engler
viscosity of 3 at 50ºC.
Extremely important. Never use brake fluid.
3.6 When the crane is not in use, it should be fully retracted in the lowest position so as to minimize piston corrosion. It is
