1. SAFETY

1.1.   GENERAL 

SAFETY

Familiarise yourself with the applications, limitations, and hazards peculiar to the press.

Maintain the press in good condition (use an authorised service agent).

Replace or repair damaged parts. Use recommended parts only

Unauthorised parts may be dangerous and will invalidate the 

  

warranty.

Keep the press clean for best and safest performance.

Locate the press in an adequate working area for its function, keep area clean and tidy and free from unrelated materials and ensure 
there is adequate lighting.

Ensure the workpiece is correctly secured before operating the press.

   Ensure that all fittings are tight before each use.

Remove ill fitting clothing. Remove ties, watches, rings, loose jewellery and contain long hair.

Keep hands and body clear of the work table when operating the press.

Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip footware.

Keep children and unauthorised persons away from the working area.

   Securely attach the press to a flat, firm, level surface capable of supporting the weight of press and any workpiece taking into account  
  clearance for workpieces.

   When not in use, release pressure from the hydraulic unit and clean the press. Stand or store the V blocks in a safe location.

DO NOT

 operate the press if any parts are missing as this may cause failure and/or possible personal injury.

     

DO NOT

 use the press for a task it is not designed to perform.

DO NOT

 make any modifications to the press.

DO NOT

 adjust or tamper with the safety valve.

DO NOT

 exceed the rated capacity of the press.

DO NOT

 apply off-centre loads.

DO NOT

 allow the workpiece or the press plates to fall from the work table.

DO NOT

 get the press wet or use in damp or wet locations or areas where there is condensation.

DO NOT

 operate the press when you are tired or under the influence of alcohol, drugs or intoxicating medication.

DO NOT

 climb upon the press.

 use to compress a spring or any other item that could disengage and cause a potential hazard including personal injury.

DO NOT

 stand directly in front of the loaded press and never leave a loaded press unattended.

allow untrained persons to operate the press.

WARNING!

 Always wear approved eye or face protection when operating the press. A full range of personal safety equipment is  

 

  available from your Sealey stockist.

DO NOT

 top up hydraulic unit with brake fluid, or any other fluid other than a good quality hydraulic oil (Sealey Part Number:  

 

  HJO500MLS/HJO5LS) as this may cause serious damage to the hydraulic unit and will  invalidate the warranty.

WARNING!

 Always position the press against a wall. If the press is situated in the open workshop, it is essential that a guard be              

     placed at the rear of the unit. This will prevent injury to bystanders in the event of the workpiece ejecting suddenly.

WARNING!

 The warnings, cautions and instructions in this manual cannot cover all possible conditions and situations that  

 

  may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this  

 

  product, but must be applied by the operator.

DANGER! 

The press is top heavy. If it requires moving after assembly or for relocation, use suitable slings around the top  

 

  crossbeam, or lift direct with a forklift with the forks located under the top crossbeam. 

DO NOT

 use a pallet truck.
