Use Maintenance 
1 Always plan the lift carefully before proceeding.
1 Store the equipment in a dry place.
2 Always check that the length and WLL stated on the sling label are suitable. 2 Ensure that seams and labelling are undamaged.
3 Examine the sling for damage and defects before use. Never use a damaged or defective sling. 3 The equipment can be cleaned by washing in a petroleum-based detergent and rinsing in water.
4 Never overload!
4 Roundslings with damaged sleeving, allowing dirt to enter, should be discarded.
5 Make sure that the load is lifted vertically, centered above the point of gravity.
5 Roundslings with broken yarns as a result of damaged sleeving must be discarded.
6 Use identical slings in case of multi-legged lifting and take the lifting angles into account when choosing equipment. 6 Roundslings must be inspected regulary for knots and irregularities, indicating yarn breakage. Discard if found.
7 Do not tie knots in slings to shorten or extend them. 7 Webbing slings: Discard in case of serious damage due to friction.
8 Never lift with twisted or entwined slings. 8 Webbing strops: Discard if/when edge wear/ damage exceeds 5% of its width.
9 Place load-bearing seams and joints between the hook and the load.
9 Webbing strops: Repair or discard when eye sleeving is worn out.
10 Protect the sling from sharp edges using edge protection or protecive sleeves.  
11 Avoid shock loading and snatch lifting.
12 Do not drag a load in the sling and do not drag slings over the ground.
13 Keep polyester slings away from alkalis (for example ammonia and caustic soda). If in doubt about exposure to chemicals, check with your supplier.
14 Do not use polyester slings in temperatures over +100°C.
15 Examine slings after use and remove from service if visible damage has been suffered.
