Uncrating the NGT-12.5
Follow the steps below to uncrate the NGT-12.5. It is recommended that you review the instructions completely
before beginning with step 1.
1. Remove the cardboard top from the shipping pallet. Remove the truss rods and any larger accessories. (You
may wish to save the foam tubing that wraps the individual rods. Cut the tubing shorter and leave it on the rods
during normal use to provide insulation—especially desirable on cold nights—and also to protect the finish during
transport.)
2. Remove the shrink wrap that holds everything stationary.
3. Remove the two cords that tie the nose assembly to the spring clips on the tub. Remove the packing material
then lift the nose assembly out and set it aside.
4. Remove the box of NGT-12.5 accessories.
5. Remove the two cords tying the tub to the handles of the base assembly.
6. Remove the dust cover from the primary mirror.
7. Remove the packing material from inside the tub, including the pieces of foam wedged between the edge of the
mirror and the side of the tub.
Do not remove the fine tissue from the mirror at this time.
8. Remove the packing material from between the bottom of the tub and the split-ring assembly.
9. Remove the protective wrapping of tape from around the three chromed counterweights located underneath the
tub. Unscrew the counterweights by turning them counter-clockwise, taking care not to tip the tub too close to
vertical, as these counterweights hold the mirror cell in place.
10. Grasp the mirror cell handles and lift the mirror and its cell out of the tub, setting it aside gently.
11. Carefully remove the protective tissue covering the primary mirror. Lift it straight up and off.
Do not drag the
tissue across the face of the mirror. Do not touch the mirror.
12. Remove the cord tied between the split-ring assembly and the latitude adjustment knob on the base assembly.
Carefully remove the packing material from between the drive roller bearings and the drive ring. Do not allow the
drive ring to drop on the drive roller bearings.
13. Remove the three bolts holding the base frame to the shipping pallet and remove the telescope from the crate.
Shipping Damage
In an effort to reduce in-transit damage, each NGT is shipped with a shock detection device called a Shockwatch
. If
the shock indicator has turned red this shows that the crate has been handled more roughly than we like. In that
case, make a notation on the delivery document (with the signature of the delivery person if possible) then contact the
carrier and JMI directly.
