Performance and Safety.  The DHS-05 and DHS-1 models are designed for rated capacity spreading. 
Both models feature high strength steel construction and spring return cylinder. A wide variety of 
applications exist for this category of product.  

Special skill, knowledge and training may be required for a specific task and the product may not be 
suitable for all jobs. The user must ultimately make the decision regarding suitability of the product 
for any given task and assume the responsibility of safety for all in the work area. Contact a Durapac

Receiving Instructions 

It is recommended prior to use that an inspection be done by qualified personnel and that any 
missing or damaged parts, decals, warning/safety labels or signs are replaced with Durapac 
authorised replacement parts only. Any spreader that appears to be damaged in any way, is worn, 
leaking or operates abnormally should be removed from service immediately until such time as 
repairs can be made. Any spreader that has been or suspected to have been subject to a shock load 
should be removed from service immediately until inspected by a Durapac authorised service centre. 
Owners and operators of this equipment should be aware that the use and subsequent repair of this 
equipment may require specialised training and knowledge.

Safety 

Save these instructions. For your safety, read and understand the information contained within. The 
owner and operator should have an understanding of this product and safe operating procedures 
before attempting to use this product. Instructions and safety information should be conveyed in the 
operator's native language before use of this product is authorised. Make certain that the operator 
thoroughly understands the inherent dangers associated with the use and misuse of the product. If 
any doubt exists as to the safe and proper use of this product as outlined in this factory authorised 
manual, remove from service immediately. 

 

DANGER: 

 

 

To avoid personal injury keep hands and feet away from work area during operation 

 

 

Do NOT 

handle pressurised hoses. Escaping oil under pressure can penetrate the skin 

causing serious injury. If oil is injected under the skin, see a doctor immediately 

 

 

Stay clear of loads supported by hydraulics. A cylinder, when used as a load lifting 
device, should never be used as a load holding device. After the load has been raised 
or lowered, it must always be supported mechanically 

 

WARNING: 

 

 

The system operating pressure must not exceed the pressure rating of the lowest 
rated component in the system. Install pressure gauges in the system to monitor
