3. Sometimes the mast mounting brackets prevent removal of the cylinders in this way In these cases the masts must be separated by a greater amount to allow the cylinders to be removed more or less vertically LIFT TEK 5 ELECARS Lift Technologies gt REPLACEMENT OF THE SEALS IN THE LATERAL CYLINDERS When it is necessary to replace the seals observe the following procedure Unscrew the cap 1 by means of the proper tool Avoid hitting it with pointed objects Pull out the rod 5 Unscrew the metal ring 9 Dismantle the piston 6 Substitute the parts 13 7 and 2 Reassemble the piston 6 and _ retighten the metal ring 9 Remount the rod 5 using the proper seal loader in according to the cylinder type and the mast type and following the indicated instruction Remove all grease and oil traces from the cap 1 Apply two drops of sealer on the thread of the cap 1 Retighten the cap NOTE WHEN THE SEAL IS REPLACED ALSO SUBSTITUTE ALL OTHER PARTS CONTAINED IN THE KIT Pag 30 of 31 REPLACEMENT OF THE SEALS IN THE DISPLACEMENT CYLINDERS In the displacement cylinder all seals are located in the cap 1 Therefore it is not generally necessary to dismantle the cylinder from the mast In the central cylinders it will be necessary to remove the chain and unscrew the chain sheave holder assembly In the lateral cylinders it is sufficient to work with the crossmember on which the r
4. This condition creates oscillations that cause the detachment of the external hardened surface in this case circumferential cracks will appear and will run completely around the roller Pag 17 of 31 LIFT TEK amp ELECARS Lift Technologies DESCRIPTION OF CONSTRUCTIVE COMPONENTS MACHINING OF PROFILES The profile is obtained with hot rolling with tightest tolerances The profile for masts with equal or upper capacity to 16 000 kg is instead obtained by welding Before using the profiles they are tested their rectangularity is checked and they are sanded to remove the superficial scale a residual from the rolling procedure TOLERANCES The strict tolerance of the internal dimensions between the running tracks permits an accurate clearance between the profile and roller During assembly the clearance value is usually lower than 0 5 mm The maximum acceptable limit is 0 7 mm Pag 18 of 31 RUN IN PERIOD If the rollers work correctly in the first phase of their employment they will produce a superficially hard surface on their tracks on the profiles An indication of the proper initial use is the shine the tracks assume after a few hours of work DESCRIPTION OF CONSTRUCTIVE COMPONENTS GREASING OF THE TRACKS At the moment to putting in service the mast the sliding tracks must be greased in order to favour a correct run in period Also later the tracks will need periodic lubrication The fre

6. E CHAINS ON CARRIAGES ON MASTS The chain must be regulated in such a way that the upper and lower stoppers never resulted engaged The type of mast construction when the chain is correctly regulated foreseen a residual clearance of about 5 mm either on upper stoppers or lower stoppers Pag 22 of 31 Therefore remove the forks and adjust the chains in such a way that between the lower stopper of the carriage and that one on the inner stage a clearance of 5 mm is present Send to end of stroke the central cylinder and verify also between the upper stoppers a minimal clearance of 1 mm is present with the load the value of the clearance will tend to increase carrying itself to 5 mm Keep in mind that if this intervention is not completed periodically and it is allowed instead the stoppers come engaged common case in the presence of attachment without forks these will finish with becoming deformed and the lower roller of the carriage can go out from the mast TAAT CLE On the other hand if too much clearance is allowed between the lower stoppers the upper ones could bind too much causing large loads on themselves the chain and in the cylinder Check the chains that work in parallel way have always the same tension in contrary case act on the appropriate chain anchor by blocking nut LIFT TEK amp ELECAR Lift Technologies a DESCRIPTION OF CONSTRUCTIVE COMPONENTS CYLINDERS The cylinders which

9. RRY OUT AFTER MOUNTING THE MAST ON THE TRUCK ATTENTION A The drainage tube must not be immersed in the reservoir below the oil level IT MUST ALWAYS BE ABOVE THE SURFACE B The drainage tube should also form a bend before entering the reservoir in which there should be a small quantity of oil to act as a syphon This helps to keep the internal surface of the cylinder case wet when it is closed The roller surfaces must be greased both where the fork carriage and the mast run For this purpose use graphite grease avoiding if possible spray greases Circulate the oil through the mast system three or four times Pag 13 of 31 Purge the air from the displacement cylinders For TV only the central cylinder for DV the central and lateral cylinders Lift the fork carriage about 500 mm Loosen the screw situated below the top cap At the first sign of oil tighten it for the mast that are provided with m l M al l Put a load on the forks 30 of the nominal load check that the descent is regular during transport the cylinder may have been damaged LIFT TEK amp ELECARS Lift Technologies gt ORDINARY MAINTENANCE Ordinary maintenance will include the following operations ROLLER TRACK LUBRICATION To be carried out every 200 working hours CHAIN LUBRICATION To be carried out every 200 working hours S DE SHIFT LUBRICATION IF FITTED To be carried out every 200 working hours
10. The O ring 13 maintains the static seal between the piston and the rod Pag 25 of 31 The dust scraper 2 stops the dirt and water from seeping into the cylinder The little seepage that might occur is directed to the reservoir tank by means of the drainage tube joined to the body 16 The drainage tube must reach the tank yet always remain just above the oil level Otherwise the cylinders could during the descent phase syphon a large quantity of oil that in the ascending phase must be expelled through the drainage connection This would create a strong counter pressure that would damage the dust scraper and would disconnect the drainage tube As already mentioned in the initial use instructions there must always be a small amount of oil in the bend of the drainage tube just before it enters the tank LIFT TEK amp ELECARS Lift Technologies a DESCRIPTION OF CONSTRUCTIVE COMPONENTS LEAKS IN THE CYLINDERS Leaks in the displacement cylinders occur toward the outside Therefore it will be very easy to recognise a damaged seal and to know when a replacement is necessary With the piston cylinders the leaks are conducted to the reservoir by the drainage tube and are not so easy to detect Pag 26 of 31 Instead it will be noticeable by a slow descent of the load The presence of oil in the drainage tube of the holding cylinders does not necessarily mean that leaks are present The drainage
