Working temperature and oil types
Standard operation temperature indicated in User manual of every truck: +5…+40 degrees Celsius
The requirements of operation temperatures are given by ISO 3691-1 standard
Types of hydraulic oil used by Noblelift factory and replacement recommendations:
All electric trucks except of Long tiller series (PTxxL/PSxxL): L-HM 46
Electric trucks of Long tiller series (PTxxL and PSxxL), SC trucks, Forklifts: L-HM 32
Hydraulic oil which recommended to be used during oil replacement for areas with relatively low ambient temperatures: L-HM 32, HLP 32, HVLP 32, L-HV 32
Hydraulic oil which is recommended to be used during oil replacement for areas with relatively high ambient temperatures: L-HM 46
Oil replacement quantity recommended by factory is linked with type of mast, not specified for every lifting height:

Chains
When a forklift truck leaf chain is in mint condition, the rivet pins and articulating link apertures are almost perfectly cylindrical in shape and have a very smooth surface finish.
This ideal state has excellent bearing properties which are necessary for smooth, quiet and efficient operation. It is inevitable, however, that a forklift truck chain will wear leading to the deterioration of these properties. When the rivet pins wear (a process known as Galling). Furthermore, the apertures in the link plates elongate.
Most leaf chain rivet pins are produced with a case hardened outer surface. It is generally accepted that a 3% worn leaf chain will lose approximately 18% of its tensile strength.
Over time the castellations will become so deep that the case hardening of the leaf chain rivet pin will be completely destroyed. Once the surface has worn away it will become considerably weaker and potentially very dangerous. It is, therefore, necessary to limit the level of acceptable leaf chain wear.
The FB professional chain wear gauge (CWG) is a precision tool that has been purposely designed for the accurate measurement of chain wear in leaf chain/forklift chain. It states in the accompanying instructions that at a percentage elongation of 2% the chain will need to be carefully monitored if it is to be still used. At 3% elongation, the chain is considered a safety risk and should be replaced immediately.

At 3% elongation, the chain is considered a safety risk and should be replaced immediately.
Chains

All links should rotate freely, chain can’t be dry
Cracks of any kind are not allowed
Corrosion is not allowed
Rotation of pins and their protraction is not allowed
Chain anchors should always be inspected carefully and replaced in case of any damages or deformations of thread or holding parts

Electromagnetic brakes
Noblelift is using the following brands of electromagnetic brakes: Reach, Intorq, Amer.
All brakes are performing functions of parking brakes only and not used as working brake.
Therefore during normal operation the wear and teat of friction disk is very small.
All brakes used by Noblelift are not adjustable. The servicing is limited by check of air gap during regular maintenance.
The air gap can be checked by filler gage and should be within 0.5 mm. If more, the friction disk need to be replaced.
Make sure the truck is placed on even solid surface and will not roll if brake is removed, Fix the wheels with wooden bars of suitable size or fixation cones.

The brake is supplied preassembled. The rubber ring “B” need to be removed. Take care of sleeves 5 and do not lose them after rubber ring removing.
Screws A are used for servicing only. Need to be removed after assembling before use of truck OR installed before disassembling of brake body

Forged Forks. Replacement criteria

Welded Forks
Welded forks need to be inspected for the possibility of cracks in welding points,
If necessary the penetrant agents (paint) need to be used to determine cracks.
In case of obvious deformations, deviations of shape, interference of forks with support arms etc. forks need to be replaced

Cylinders and seals
Use special tools to remove seals from cylinder in order to avoid damages of sealing surfaces/
Use special tools to install seals in cylinders to prevent sealing lips from damages against of tread and sharp edges.
All tools must be free of burrs

Mast and rollers adjustment
A truck should be located on even surface, the mast shouldn’t be tilted otherwise the adjustment will be not correct.
Using the filler gage measure and set the distance between side rollers and side surface of profiles within 0.5 mm. Make sure that neither mast section nor fork carriage are tilted during this adjustment – Keep parts in parallel.
As there can be deviation in width of sections lift and lower the forks from bottom to the end and check that movement of forks and mast sections is smooth and not sticking. If necessary – increase the side gap to avoid jerks.
In order to grease the mast firstly the profiles need to be cleaned and old grease need to be removed, then the rollers’ tracks need to be greased fully.

Lubricants
The list of lubricants is given as recommendation only.
Any lubricant with suitable application purpose and properties can be used.

Contactors
Contacts of contactors are subjects of natural wear and tear.
If the silver coating is worn out or damaged, the contactor need to be replaced.
The cleaning of contacts from results of burning (blackened and other defects) will not solve the problem and generally will cause the wear even faster.
Springs of contactor must be free of any defects and corrosion.
In order to check the coil measure its resistance. If the resistance is endless or no resistance recorded – the coil is damaged and contactor needs to be replaced.
