MAST DEPLOYMENT (3 Man Operation)
1. Select a site that has no more than a 15
degree (26.8%) slope, is suitable for
deployment of guy stakes and guy lines and
is at least 80 ft. (24.4 m) from overhead
power lines.
2. Remove the accessories from the accessory
bag. Refer to the accessory sheet for part
identification and quantity.
3. Place the base plate at the center of the site
and anchor with four base plate spikes.
4. Hook loop #1 of the radius rope over the
center post of the base plate and unwind it to
loop #2. See Fig. 1.
5. Hammer one guy stake at a 60 degree angle
at the loop #2 position. See Fig. 1 & Fig. 2.
6. Unwind the radius rope to loop #3 and hook
loop #3 over the guy stake that was just
placed. See Fig. 3.
7. Hammer one guy stake at a 60 degree angle
at the loop #2 position. See Fig. 2 and Fig. 3.
8. Without moving loops #1 and #3, walk loop
#2 to the opposite side of the base plate and
hammer one guy stake at a 60 degree angle
at the loop #2 position. See Fig. 4.
9. Repeat steps 4 through 8 except using loops
#4 and #5. See Fig. 5 and Fig. 6.
10. Place the support stand over one of the inner
guy stakes. See Fig. 7.
11. Place the mast gearbox on the base plate and
lay the top end of the mast on the support
stand. See Fig. 7.
12. Install the payload and secure it.
13. Place the cable(s) through the cable guides
and attach to the payload as required. See
Fig. 8.
14. Unwrap the three inner guy tensioners and
attach the black snap hooks to the lower (6”)
guy plate (black) and the green snap hooks
to the lowest hole on the inner guy stakes.
Note that the snap hooks should be fastened
from underneath the guy plate. See Fig. 8
and Fig. 10.
15. Unwrap the three outer guy tensioners and
attach the gr een snap hooks on the single
line side to the upper (2.0”) guy plate
(green) and the green snap hooks on the
double line side to the lowest hole on the
outer guy stakes. Note that the snap hooks
should be fa s tened from underneath the guy
plate. See Fig. 8 and Fig. 12.
16. Raise the mast to a vertical position and
verify that the gearbox is securely seated on
the base plate. See Fig. 9.

17. Remove the s lack in one o f t he inner guy
tensioners by winding t he trailing end of the
guy line around the tensioner. See Fig. 10.
18. Tension the line by sliding the tensioner
toward the guy stake and lo ck it by placi ng
the guy tensioner hook over the double guy
lines. See Fig. 11.
19. Repeat for t he other inner guy tensioners.
20. Using the bubble level, make final
adjustments to the guy lines to set the mast
vertical. The bubble must be completely
inside the inner circle on the indicator before
the mast is extended. See Figs. 14 and. 15.
21. Place the hand cran k onto the gearbox and
crank counterclockwise to extend the mast.
Maintain a steady, even cranking speed. In
the event of a jam, stop and crank in the
reverse direction approximately five turns,
then retry. Cranki ng mo r e slo wl y will he lp
to clear a jam. See Fig 14 and Fig. 15.
22. Under windy conditions, more torque will
be required to extend the mast, especially
when a sect ion is nearing full extension. If
available, deploy two men to the appropriate
upper guy lines to pull the mast into the
wind and straighten it. This will red uce the
torque required for deployment. Do not
attempt to deploy the mast if winds exceed
25 mph (40 kph).
23. The mast has built-in stops at approximately
32 ft., 10 in. (10 m), but it can be extended
to any intermediate height.
24. Once the mast has reached the desired
height, remove the crank.
25. Remove the slack in one of the outer guy
tensioners by winding the trailing end of the
guy line around the tensioner. See Fig. 12.
26. Tension the l ine by sliding the tensioner
toward the mast and lock it by placing t he
guy tensio ner hook over the double guy
lines. See Fig. 13.
27. Repeat for the other outer guy tensioners.
28. Visually check that the mast is str a ight in all
directions. Adjust the outer gu y tens ioners
as required to straighten the mast.

MAST RETRIEVAL (3 Man Operation)
TP-4659301-00
TP-4659301-00
1. Verify that winds do not exceed 25 mph (40 kph). Do not attempt to retrieve the mast in winds exceeding 25 mph (40
kph)
2. Release the three outer guy tensioners to slacken the upper guy lines. (Ref. Fig. 12 and Fig. 13)
3. Place the hand crank onto the gearbox and crank clockwise to retract the mast. Maintain a steady, even cranking
speed. In the event of a jam, stop and crank in the reverse direction approximately five turns, then retry. Cranking
more slowly will help to clear a jam. (Ref. Fig. 15)
4. Under windy conditions, more torque will be required to retract the mast, especially when a section is still fully
extended. If available, deploy two men to the appropriate upper guy lines to pull the mast into the wind and straighten
it. This will reduce the torque required for retraction.
5. After the mast is fully nested, hold the mast vertical and release the three inner guy tensioners to slacken the lower
guy lines. (Ref. Fig. 10 and Fig. 11)
6. Unhook all of the guy tensioners from the guy stakes.
7. Set up the sup port stand over one of the inner guy sta kes. (Ref. Fig. 7)
8. Lower the mast until it rests securely on the support stand . N ote that the mast will only tilt in the direction away from
the gearbox crank input, rotate the mast if necessary to lower it into the support stand. (Ref. Fig. 7)
9. Remove the payload and stow it.
10. Unhook the guy lines from the mast guy plates and wind the guy lines around the guy tensioners for storage.
11. Place the “mast head end” of the mast transport bag (as labeled) over the top of the mast.
12. Remove the mast from the supp ort stand and place it into the transport bag.
13. Hit each guy stake once on each edge (not on the inside or outside curved surfaces) then use the hammer to pry under
the guy line hook rib and remove the guy stake. (Ref. F ig. 2)
14. Remove the base plate and base plate spikes.
15. Stow all the accessories in the accessory bag. Refer to the accessory sheet for part identification and quantity
verification. Close the accessory bag.
16. Place this sheet in the pocket of the mast transport bag and close the bag.
PREVENTATIVE MAINTENANCE CHECKS AND SERVICES
1. Keep the mast clean. The sections can be wiped down during deployment or retrieval as required. Use care to avoid
pinch points around the collars.
2. If the locks become hard to operate or require cleaning, the lock housings and posts can be removed while the mast is
fully nested using the balldrivers in the accessory kit. Use care not to lose any of the small parts contained in the lock.
Never remove a lock while the mast is deployed. (Ref. Fig. 8)
3. The bottom of the gearbox must be kept clean to ensure that it seats properly on the base plate.
4. Perform the following checks before and after each deployment. Do not attempt to deploy the mast if it does not pass
all of the following checks.
(a) Visually inspect the guy tensioners for frayed or broken rope, cracks or other damage.
(b) Visually inspect the crank handle for damage.
(c) Visually inspect the guy plates for cracks or elongated holes. (Ref. Fig. 8)
(d) Visually inspect the guy stakes for cracks or severe damage.
(e) Visually inspect the exterior of the mas t for dents or other damage.
(f) Visually inspect the mast for loose, broken, or missing hardware.
(g) Visually inspect the gearbox for damage.
(h) Verify that the bubble level is attached to the gearbox and is operational. (Ref. Fig. 15)

Mechanical Mast Operating Instructions
Do not deploy the mast if power lines are less than 80 ft. (24.4 m) from
the center of the deployment site.
Do not attempt to deploy the mast on soft or loose soil. The base plate
and guy stakes could become unstable under wind loading and cause
the mast to fall.
Do not attempt to deploy or retrieve this mast during electrical storms
or when winds exceed 25 mph (40 kph)
Helmets or hard hats, eye protection, gloves, and safety shoes or
combat boots must be worn while working in the mast deployment
area.
Do not attempt to deploy the mast on ground that slopes more than 15
degrees (26.8%).
The mast must be vertical before deployment. Adjust guy lines as
required until the bubble level indicates the mast is vertical.
The mast weighs approximately 42 lbs. (19 kg). Always observe
weight lift limits.
