Lag and Anchor Bolts

All anchor bolts must be installed in accordance
with  the  manufacturer’s  instructions  and  local
codes  and  regulations.      Improper  installation
may result in serious injury or death.

Do  not  install  anchor  bolts  in  cracks  or
expansion  joints  in  concrete.    Anchors  may
come  loose  or  pull  out  and  the  dock  lift  would
become  unstable  and  may  result  in  serious
injury or death.

7. Drill anchor hole to diameter and depth per the

manufacturers specifications.  Use a min. of 3/4”
diameter  anchor  bolts.      All  anchor  bolt  lengths
must suit local codes and conditions.  Type and
depth of concrete will determine type and length
of anchor bolts required.  (See

FIGURE #3

)

8. With the nut and washer in place, insert the

anchor bolt and tap into position. Tighten to
manufacturers specifications.

Keep all hydraulic oil and lines free of dirt, moisture
and any type of contamination.  Be sure to flush all
hydraulic  lines  before  connecting  External  Power
lines  as  they  could  have  become  contaminated
during shipping or installation.  Dirt or moisture can
damage the pump or valves in the hydraulic system
or cause other problems in the hydraulic system.

9. Install the power unit in its desired location.

External  power  units  are  shipped  standard  with
mounting  brackets  to  install  to  the  floor.    The
brackets can either be bolted through, welded to
a  steel  floor  or  anchor  bolted  into  a  concrete
floor.    Optional  wall  mount  brackets  are
available.

10. Connect all hydraulic lines as required. Make

sure to blow out all lines prior to connection with
compressed air or flush with hydraulic fluid.

Use correct hydraulic fluid as stated in this manual.
(See FIGURE # ) If incompatible hydraulic oil is
used damage to the hydraulic system could occur.

Make sure that all hydraulic lines are free of the
dock lift during operation. A pinched or cut
hydraulic line could cause the lift table to lower
suddenly causing serious injury or death.

Never  place  any  body  part  near  the  hydraulic
system  to  test  or  look  for  damaged  or  leaking
hydraulic lines or equipment.  Exposure to high
pressure hydraulic fluid will pierce through skin
and enter the blood stream causing death.

Only  qualified  electricians  are  to  work  with  any
electrical  parts.      The  dock  lift  power  supplies
can  be  up  to  460  Volts  AC,  this  voltage  will
cause death.

Fusing  requirements  are  shown  in  FIGURE  #5,
all  fuse  sizes  are  calculated  to  work  safely  per
NEC  specifications.    Failure  to  fuse  properly
could  result  in  fire  or  electrical  shock.  Serious
injury or death could occur.

11. See fusing table

(FIGURE #5)

for correct fuse

sizing. Always use the correct fuse and wire
size for connections.

12. Follow all wiring diagrams located in this manual

to make permanent electrical connections.

13. Always verify that in 3-phase motors the motor is

turning  in  the  correct  direction  as  shown  on  the
motor  housing  or  pump.    If  the  motor  is  not
turning  in  the  correct  direction  STOP,  do  not
operate.    Change  any  two  of  the  three-phase
leads to change motor direction.  If this does not
