8-4 Check of stroke
When the tool is being used, hydraulic oil is running short, and it causes
shortage of stroke.
Shoratage of stroke may cause decrease in POP Nut torque.
Check the stroke once a day before work by following procedure.
If stroke is short, refer to p.12 and adjust stroke.
≪
Procedure
≫
Fasten POP Nuts on actual material or testpiece (same thickness and
material ), and check m’ length (see p.15)
If stroke is short, adjust it with p.14.
8-5 Lubrication
Proper lubrication stabilizes the function of valve part and makes long the
life of air motor and seals
Check the amount of lubricating oil and drip.
When the lubricator is set in hose within 3m of the tool, check the
amount of lubricate oil and drip every day before work.
Amount of drip is 1
〜
2 drops per 10
〜
20 POP Nut fastenings.
Supply of lubricate oil to coupler plug
When lubricator is not set in hose or not able to set within 3m of the tool,
supply turbine oil (ISO VG32) to coupler plug every after 500 POP Nut
fastenings by following procedure.
