INRODUCTION
This is a modular system built around a hydraulic cylinder delivering a
working pressure of 17 ton, to remove and install drive shaft, wheel hubs,
wheel bearings, silent blocks and suspension ball joints in a safe and
ecient way. Some accessory tools are specially made for this hydraulic
system while other are sold as tool sets to be manually operated as well as
hydraulically. This manual gives a general introduction to the tool system
and how to handle it, while more detailed information such as spare part
lists for a specific tool can be found on our web and in the packaging of a
new tool.
SAFETY AND PRECAUTION
• Read this manual completely before starting to assembly
and use the tools.
• Always keep in mind that this hydraulic cylinder produces up to 17 ton
of pressure. This puts very high demands on securing that all tools attached to the cylinder and the workpiece are aligned and can not slip or
in any other way cause danger.
• Always follow instructions provided by the vehicle manufacturer
regarding handling and safety measures.
• Use eye protection and safety gloves.
• The tool is not designed for use together with impact wrenches.
• Do not knock on any part of the tool during load.
• Keep this equipment out of reach for children.
Only authorized persons that have read and understood these instructions
should operate the hydraulic tools. Kamasa Tools does not take responsibility for damage or injuries caused by unsafe use, lack of maintenance or
use together with components not designed to be used with this tool.

OPERATION INSTRUCTIONS
• It’s very important not to exceed maximum inlet air pressure of
8,5 bar (120 psi).
• In order to avoid damage to adapters, fittings and manometer, these
parts are not mounted to the cylinder and pump at delivery. Use sealing tape or liquid thread sealant on the parts that are screwed on the
cylinder/ pump and check that there are no leaks once the system is
connected to compressed air.
• Fill the oil pump with 1600 ml hydraulic oil SAE 10.
• Connect pump, hose and cylinder before connecting the compressed air
and test run the system before use.
• Press the pedal backward to apply hydraulic pressure to the cylinder.
Release pressure by pushing the pedal forward, RELEASE
• If the system needs priming, push the pedal forward, RELEASE mode
and press the valve under the back of the pedal for 15 seconds, this
operation will prime the system.
• Operations that can be performed by the hydraulic system in combination with Kamasa Tools special tools are described on the following
pages.
MAINTENANCE
• Never attempt to disengage parts of the system or disassemble
the pump or cylinder before disconnecting the air pressure.
• Check the system periodically for hydraulic or air leaks.
• Release air pressure when stored.
