SAFETY Safety Symbols used in the Manual To help guide you through the manual and to highlight particular danger areas, we have used graphic illustrations:
General Maintenance and Repair Safety Notes DANGER
DANGER This symbol indicates life-threatening risks ●
●
Failure to comply with this notice may result in fatal injuries to yourself or other people.
WARNING This symbol indicates the risk of serious injury and/or serious material damage. ●
Read the safety notices in the truck Maintenance and Operator's Manuals.
Failure to comply with this notice may result in severe injuries to yourself or other people and/or serious material damage.
CAUTION
Motorised vehicles can be dangerous if maintenance and service are neglected. For this reason maintenance and inspections must be carried out at regular short intervals by trained personnel working to approved company guidelines.
DANGER Follow all national/local safety regulations applicable for maintenance work, e.g. for work on higher levels. ●
This symbol indicates the risk of minor injury and/or minor material damage. ●
Failure to comply with this notice may result in minor injuries to yourself or other people and/or minor material damage.
1.
Maintenance work must only be carried out in accordance with the test and maintenance program contained in the present Maintenance Manual and any applicable service notices.
2.
Only qualified and authorised personnel may carry out work on the truck.
3.
Always keep fire extinguishers in good working condition. Do not approach fluid levels or leaks with a naked flame.
4.
To clean, use a non flammable, non combustible cleaning solution which is groundwater-neutral. Only carry out cleaning with an oil separator. Protect the electrical system from dampness.
5.
Keep the service area clean, dry and wellventilated.
6.
Do not allow oil to penetrate the ground or enter the draining system. Used oil must be recycled. Oil filters and desiccants must be treated as special waste products. Relevant applicable regulations must be followed.
7.
Neutralise and thoroughly rinse any spilled battery fluid immediately.
8.
Keep the truck clean. This will facilitate the location of loose or faulty components.
OPTION These items relate to optional features not supplied with the standard version.

SAFETY 9.
Make sure that capacity and data plates, warnings and labels are legible at all times.
10. Alterations or modifications by the owner or operator are not permitted without the express written authorisation from Crown. 11. Only use original Crown spare parts to ensure the reliability, safety and suitability of the Crown truck.
Before Leaving the Truck ●
Stop the truck.
●
Lower the fork carriage fully.
●
Apply the parking brake.
●
Turn off the truck and remove the key.
●
Block all wheels when parking on an uneven surface.
Warnings and Labels on the Truck During regular maintenance check that the warnings and labels on the truck are complete and legible. ●
Clean any illegible labels.
●
Replace any faulty or missing labels.
The order and meaning of the warnings and labels on the truck are described in section 10.9 of the parts manual.
Before Carrying out Work on the Truck ●
Raise the truck to free the drive wheel. Press the emergency Stop button and disconnect the battery.
●
Prevent the truck from rolling away.
●
Before carrying out work on the hoist frame, the lift mast or on the fork carriage: Block these parts according to maintenance instructions in order to prevent them from dropping.
●
Only carry out operational testing when there is sufficient room to manoeuvre, to avoid the risk of injury to yourself and others.
Before Operating the Truck ●
Check the safety devices.
●
Get into the driver's seat.
●
Check the operation of the lifting device, travel direction switch, speed control, steering, warning devices and brakes.

INTRODUCTION General The present manual is designed for Customer Service engineers who wish to familiarise themselves with the maintenance work required for the various truck components. It also contains troubleshooting sections which can be used to identify and remedy truck faults.
INFORMATION This book is not an operating manual. It is designed solely for specialist personnel who have been trained and authorised to carry out the work described in the manual.
This information can be found on the truck's data plate. Only if this information is provided can the order be processed quickly, correctly and reliably. Please refer to the Technical Specifications Sheet for the utilisable loads, technical data and dimensions for thisseries. Brochures can be obtained from your CROWN dealer or from the following address:
CROWN Gabelstapler GmbH & Co.KG Moosacher Str. 52 80809 Munich GERMANY Tel.: +49 (0)89 / 93 002 -0 Fax: +49 (0)89 / 93 002 -175 or133
Using the Manual This manual therefore contains fewer and less detailed warnings than the Operator's Manual, as the latter is aimed at persons who have very little or no prior experience at all.
Operating Instructions This manual contains no operating instructions. An operating instructions manual is supplied with the vehicle. Additional copies can be ordered as required. With the help of this manual you and your personnel will be able to ensure the long service life, operational safety and error free functioning of your CROWN vehicle.
Service Training CROWN offers the appropriate vehicle related training for service personnel. Details on this training can be obtained from CROWN on request.
Ordering Spare Parts The maintenance manual does not cover spare parts. These are listed in a separate manual.
The manual is divided into sections. The following table shows how the manual is structured. Sections Maintenance Section

LUBRIFICATION AND ADJUSTMENT Lifting and Blocking
INFORMATION
WARNING
To raise truck for additional jack clearance, fabricate a 1/2" board for load wheel or 3/4" board for drive wheel (8" x 12" with stop and bevel). Drive truck onto board and proceed with step 3. If truck can not be moved, use overhead lifting device for additional jack clearance.
Always support a raised truck with wooden blocks or other appropriate equipment to relieve the jack. ●
Move truck to a secure non traffic maintenance area with a level floor.
●
No load on forks.
●
Disconnect the battery and prevent the truck from being switched on again.

LUBRIFICATION AND ADJUSTMENT Restoring the Truck to Service Recommended Lubricants and Oils When restoring the truck to service, proceed as follows:
Lubricants The following page lists typical lubricants which are also used by Crown in the factory. However, any lubricants with the same technical specifications can be used.
Cold Store Trucks Special hydraulic oil, lubricant oils and grease for low temperature applications must be used for cold store trucks (see table on following page). All screws, washers, nuts, pins, retaining rings etc. must be treated regularly with an anti-corrosion solution CROWN no. 805236004. Electrical connections and components must be carefully protected against corrosion. For more details refer to chapter 4.
*
●
Remove any addition corrosion protection applied (except for cold store protection)*.
●
Jack up the truck, remove the wooden blocks and lower the truck.
●
Charge the battery or install a charged battery.
●
Connect the battery.
●
Carry out the daily check. Do not use high pressure cleaners and/or solvents on the truck. Do not use metal brushes. Do not wetclean the electrical system and do not use flamma ble cleaning solutions.
Maintenance intervals must be adapted to the conditions of use. They should be as frequent as possible to prevent excess wear.
Truck Decommissioning When taking the truck out of service for more than 3 months, proceed as follows: ●
Disconnect the battery.
●
Decommission the battery in accordance with the manufacturer's instructions.
●
Clean the truck*). Wipe off any grease in accordance with the maintenance manual.
●
If the truck is to be stored in hostile ambient conditions (e.g. saline atmosphere) treat the surfaces of the truck with a suitable solution to prevent corrosion.
●
Jack up the truck. Lower the chassis onto suitable wooden blocks in order to clear the wheels from the ground (this prevents the wheels from flattening under constant pressure).
●
Every 3 months connect the battery, carry out a daily check and test the truck functions. Then disconnect the battery again.
