3.2 Precautions during Stainless Steel Fastener Installation
：
Improper operation may lead to deadlock of Bolts and Nuts. Follow the steps below to
reduce this risk
1
．
Reduce the friction coefficient:
（
1
）
Ensure that the thread surface is clean ( no dirt or contaminant )
（
2
）
Apply lubricant (grease or 40# engine oil) to fasteners prior tightening to avoid galling
or seizing in the threads;

．
General installation instructions:
（
1
）
Apply force to fasteners in the direction of thread;
（
2
）
Apply force uniformly, to maintain required torque;
（
3
）
Professional tools and tool belts are recommended;
（
4
）

Safe Torques
Please refer to safe torques defined in this guide. In case power tools are required, Clenergy
recommends the use of low speed only. High speed and impact drivers increase the risk of
bolt galling (deadlock) If deadlock occurs and you need to cut fasteners please make sure
that there is no load on the fastener before you cut it. Avoid damaging the anodized or
galvanized surfaces.
