➀
Choose the proper location to dig for the concrete footing. When choosing
the exact position to dig, make sure to maximize the amount of playing
surface while minimizing possible driveway obstruction.
➁
Dig hole 42" deep and 24" square. Be sure to bell out the bottom 12" of
the hole to give added stability to the footing.
NOTE:
If you live in an area where the frost line is below 42" it is advisable to
dig to normal frost line.
Do not cheat
on the hole size: It is imperative that the
hole be a minimum of 42" deep and 24" square!
➂
Assemble the anchor kit as shown in Fig. B (page 2). Thread a
5

" hex nut
(L) 2½" of the way onto each J-Bolt (K). Place the threaded end of each J-
Bolt through the 4 holes located in the anchor template (M). Then thread a
second
5
/
8
" nut onto each J-Bolt until tight against the template, making
sure to keep the J-Bolt hooks pointing in toward the center of the tem-
plate.
➃
For this step you will need: Level; Broomstick; Tape Measure. The 42" x
24" anchor footing will require approximately ½ yard of 3000 psi concrete
(30-32 60# sacks of premix concrete). More will be needed if you dig a
larger hole. Make certain that you have enough concrete to fi nish the job.
Allowing a portion to dry while you purchase more concrete will weaken
the
footing.
➄
Mix the concrete according to the instructions on the bag. It is better to
mix it slightly wet than too dry. Fill the hole full to ground level with as little
time between batches as possible. Insert the broomstick in 3 or 4 different
places and vibrate up and down to settle the concrete. Submerge the (4)
anchor footing rebar pieces (N) into the center of the hole spaced evenly.
Next, set the anchor bolt assembly into the wet concrete, vibrate it as it
goes in to make sure the concrete fi lls in around the J-Bolt hooks. Make
sure the template is pressed fi rmly against the top of the wet concrete.
Use the level to ensure that it is level in all directions. Additionally, the
center line of the J-Bolts must be parallel with the edge of the playing
surface (see Fig. C, page 2).
STOP HERE! Allow footing to cure for seven days before proceeding.
➅
Take off the top

card
it.
➆
Thread a second

" nut on to each J-Bolt down against
the nut embedded in the concrete.
➇
Place the vertical post (A) down over the footing making
sure not to damage the J-Bolt threads. Using (4)

➈
Level the vertical post by adjusting the
5
/

" nuts located
underneath the base plate. Then tighten top nuts against
the top side of the base plate.
➉
Attach both pivot stop caps (W) over the ends of the square
blocks (pivot stops) welded near the upper end of the post.
IMPORTANT: FROM THIS POINT FORWARD DURING
ASSEMBLY, BE SURE TO SPREAD A GENEROUS LAYER
OF ANTI-SEIZE LUBRICANT OVER THE ENTIRE SHAFT
OF EACH ½” HEX BOLT. THIS LUBRICANT WILL GUARD
AGAINST RUST, AND HELP ENSURE PROPER PIVOT OP-
ERATION IN YEARS TO COME. NOTICE: Anti-Seize lubricant
is EXTREMELY MESSY. An old toothbrush, etc. may be used
to smear lubricant onto bolts instead of using your fi nger. Have
clean up rags available.
Slide the main arm (B) over the top of the vertical post and
attach to the lower pivot tube with a ½" x 10" hex bolt (H)
and ½" locknut (J). Be sure to smear lubricant on bolt
shaft.
Slide the hole located in the rim height indicator (T) (black plastic with
hole in one end) over one of the second set of welded tubes in the main
arm. Attach the spring-assist cartridge (E) to the second set of attachment
holes on both the main arm and the vertical post welded tabs utilizing a
½" x 10" hex bolt (H) and a ½" x 4½" hex bolt (G). Tighten each with a ½"
locknut (J). The rim height indicator should now hang freely along side the
spring-assist cartridge. Be sure to smear lubricant on bolt shaft.
Next attach the hand crank adjustment cylinder (F) using a ½" x 10" hex
bolt (H) and ½" x 4½" hex bolt (G). Tighten each with a ½" locknut (J).
Next, remove and discard the wooden spreader block from the spring-as-
sist cartridge. Be sure to smear lubricant on bolt shaft.

wooden spreader blocks from spring-assists until instructed to do so.
➂
Injury may occur if linkages are allowed to fall off main arm during as-
sembly. Be sure to smear lubricant on bolt shaft.
➃
Allow concrete footing to cure for seven days before completing
installation. It is advisable to wait up to two weeks to allow the anchor
footing to fully cure before aggressive play.
