Servicing of hydraulic equipment must only be undertaken by a qualified technician.
DO NOT drop or place heavy objects on a hydraulic hose, as this may cause
internal damage, which could result in rupture of the pressurised hose. A
ruptured hose could cause significant damage to components and possible
severe injury to personal operating nearby.
DO NOT let familiarity gained with any hydraulic tools allow you to become complacent.
Complacency with any tooling can result in a lack of discipline toward working guidelines and safety
principles.
ALWAYS operate the system under no-load conditions before the actual operation, to ensure there
is no air trapped in the hydraulic circuit.
DO NOT remove any labels from the product. Replace any damaged or unreadable labels
immediately.
Avoid loose clothing and jewellery that could get caught in moving parts, tie back long hair.
2.4 Hydraulic Torque Wrench Specific Safety Precautions
Failure to observe and obey the following safety precautions could result
in property damage, serious personal injury or death;
NEVER exceed the maximum rated pressure of any hydraulic equipment. Hi-Force manufactures
its TWS-N torque wrenches to operate at a maximum working pressure of 700 bar (10,000 psi).
DO NOT connect a pump with a higher pressure capacity rating to any Hi-Force tool of this model
series.
NEVER attempt to connect or disconnect, hydraulic equipment while the system is under pressure.
DO NOT weld any items to the torque wrench or modify it in any way from its delivered condition.
Your warranty may be invalidated, and it could lead to serious personal injury.
ALWAYS ensure there is clear communication between the pump operator and the tool operator.
DO NOT operate the pump unless the tool operator indicates it is safe to do so.
Take extra care when multiple tools are being operated by a single pump. Make sure all tool
operators have given the go-ahead before operating the pump.
NEVER operate the torque wrench without both hydraulic hoses connected to it.
This tool will exert very large reaction forces. Use proper mechanical support and correct reaction
arm positioning to control these forces. DO NOT position the reaction arm so that it tilts the tool off
the axis of the bolt and NEVER use the uni-swivel coupling as a reaction point.
NEVER attempt to use your hands or any other body parts as a reaction point for the tool during
operation.
This tool is NOT ATEX RATED. I.e. NOT suitable for work which takes place in explosive
environments.
