2.3 Installation Precautions
2.3.1 Stainless Steel Fastener Installation Precautions
Improper operation may lead to deadlock of Bolts and Nuts. Follow the steps
below to reduce this risk
- 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）Avoid using electric tools for final tightening;
（5）Avoid working at high temperatures,
- Safe Torques
Please refer to safe torques defined in this guide as shown in below figure. 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.

2.3.2 Ground Screw Installation Precautions
All ground screws for the projects are hot dipped galvanized to offer good look
and reliable corrosive resistance, please pay attention to below tips:
- In order to protect the Zin coating of ground screws from scratches and
peeling. Please be careful while unloading.
- In order to protect the ground screws from coating wear and structural
deformation, DO NOT pile the ground screws forcefully while there are large
roc
i
ks.
- Please apply Zin-rich paint on the surface of ground screws if necessary. And
Clenergy will not be liable to the scratches and peeling on the coating surface
of ground screws that caused by improperly unloading and piling in the
construction site.

4. Installation Instructions
4.1 Ground Screw Installation
4.1.1 Before the
installation, please
prepare necessary
installation tools &
products, and ensure that
hydraulic pile driver can
work normally in
installation site. Read the
relevant engineering
materials; get the project
layout information such as
piling depth, column span,
etc. If you have any
questions, please contact
and consult the customer
service.
4.1.2 According to the
installation planning, use
Total station (or any
instrument of similar
functions) to carry out
positioning mark and mark
out the piling position of
each ground screw. Check
the mark position before
piling, to ensure accuracy.
4.1.3 Make necessary
adjustment to make sure
that all ground screw are
on the same level and are
all aligned.
Figure 1
Figure 2
Piling depth, horizontal and vertical position of Ground screws
are determined by the engineering drawings of specific projects
If cannot eliminate the deviation of
Ground Screw, its maximum
allowable deviation should in the
range of adjustment shown in below
Figure 7.
