in the figure and denotes the minimum permitted value of the disc height.
Maximal permitted outline wear is 5% of the height H2. If a lift chain reaches the maximum level of wear, the chain should be replaced.
The nominal and minimum disc heights for respective lift chains are stated in the table in the chapter “Stretching”.
Stretching
The amount of stretch on a lift chain is measured on the part of the chain that runs over the chain sprocket. The amount of stretch may, at the most, be 2% on the most worn section of the chain. Measurement is suitably made over 300-1000 mm of the chain.
The nominal and maximum permitted chain lengths for lift chains are stated in the table below.
Wear to the bolts and around the holes on the discs are a reason why the chain stretches. The chain should be replaced if stretching is more than 2%.

Damage
The chain should be replaced if damaged in any way.
Damaged discs
If a disc has broken on the chain, this can be due to overloading or corrosion.
The chain should be replaced.
Damaged bolts
It can be difficult to discover whether a bolt has broken. It can appear as bolt rotation and/or that the outer disc is loose.
The chain should be replaced.
Dirty chain
If a chain is very dirty it is first and foremost recommended that it is replaced. It can also be dismantled and cleaned as set out in the chapter “Cleaning”.
12.3.3 Cleaning
If a chain is very dirty it is recommended that it is replaced.
Dirty chains should be cleaned before they are lubricated, e.g. by washing with solvent such as diesel or petrol.
The chain should be blown dry using compressed air and lubricated directly after cleaning
NOTE!
Exercise care with degreasing agent as these can contain abrasives.
12.3.4 Lubrication
Mineral and synthetic oils can be used to relubricate Rexnord chains. NOTE!
Lubricant must not contain substances such as molybdenum disulphide, PTFE or the like.
A lift chain should be offloaded from the weight of the fork carriage (hanging free) when lubricated.
• Lubrication intervals:
-500 hours with normal operations
-100 hours when driving in rugged environments such as cold stores and corrosive environments.
The chains are sprayed with lubricant. Note the entire chain must be lubricated, even the fastening bolts. It is especially important that the part of the chain which runs over the chain sprocket is well lubricated. The lubricate must comply with the viscosity demands at respective temperatures as set out in the table below. The following lubricants are recommended:
Anticorit
Anticorit
160, Fuchs DEA Rexoil, Rexnord Kette
* Equivalent products from another manufacturer may be used.
Do not use a special rust protective agent to prevent rust on the lift chains. These agents impair the lubrication of the chains. Regular lubrication is the best method to prevent rust attack.

13.1 Automatic height adjustment
13.1.1 General
The truck can be fitted with a photocell, which in the automatic mode controls lifting and lowering of the forks to maintain a preset height when the sensor detects the load.
The photocell is located in the holder (C) on the mast.
•Set an ergonomically correct work height by moving the holder up or down to the desired height.
Accessories – 9000 Automatic height adjustment
The holder features an emergency stop switch (D) and an indicator lamp (E), which lights when the function is active.
•Depress the emergency stop switch to switch off all truck functions.
The controls for automatic height adjustment are placed on the tiller arm.
•Lift the forks by pressing A. They will then be lifted automatically until the photocell detects the load.
•Lower the forks by pressing B. They will then be lowered automatically until the photocell detects the load.
The truck has an end position switch that switches off the pump when the forks reach the maximum lift height.
The truck has one more end position switch that detects when the forks reach the safety clearance to the ground. To lower the forks further and prevent crushing the operator's feet, further lowering must be performed manually.
Lifting/lowering of the forks can also be done in the same way as on a standard truck. When manual operation is switched on, automatic operation is cancelled.

14- Destruction instructions
14.1 General
These instructions have been drawn up as part of the truck manufacturer’s environmental management program. An important motive is, by taking nature into consideration, to economise with resources. In other words, you should try to recycle all material as far as possible. This is to minimise the discharge of environmentally-hazardous substances.
The dismantling instructions are divided into different C-codes (parts and functions on the truck.) These C-codes are:
•0000 Chassis
•1000 Motors
•2000 Transmission/drive transmission
•3000 Brakes/belt/wheel system
•4000 Steering system
•5000 Electrical system
•6000 Hydraulics/pneumatics
•7000 Working function - lift mast
•8000 Auxiliary/installation equipment
•9000 Accessories/extra equipment
The instructions do not tell you the type of material the parts are made of, but refer you to different material containers where the parts should be collected. Some plastics are marked, which means some instructions refer to the marking to determine the collection container to use.
14.2 Procedure
When sorting a component part you must know what plastic parts, liquids, environmentally-hazardous substances and metals it incorporates.
