Safety Stoplock and Release Pin - Prevents lowering the elevation below 35 degrees above the horizontal unless the release pin is pulled. The release pin should be pulled before reaching how many degrees?
2.1 D. 35 degrees. Note: The New Yorker Multiversal is designed with a safety stop at 35 degrees above horizontal to maintain stability when used in the portable base. Do not release the elevation stop and operate below that point unless the unit is secured in the truck mount fixture, or is securely restrained by ropes. No operation below the horizontal shall be attempted unless the unit is secured in the truck mount.
Horizontal Friction Lock - When tightened, holds the Multiversal Nozzle in a stationary position; if released, permits ___degrees to be traversed horizontally.

The portable ground base should be placed at the point of operation with the front leg pointing toward the fire or desired point of operation.
How do we tell which leg is the front leg?
3.3.1
The leg with the safety chain attached
To prevent backward movement of the Multiversal Nozzle, it must be secured in position by means of a utility rope, in the following manner:
A. Place the middle of the rope on top of the siamese, over the identification plate.
B. Bring the two sides of the rope under the siamese and up between the two inlets.
C. Bring the two sides of the rope up over the siamese and bring each side forward to the large leg of the ground base on each side of the front leg.
Make a half hitch on each of these two legs.
D. Bring the rest of each end of the rope forward, and secure each end to a substantial object which is forward and at an angle to the nozzle, using what knot?
3.3.5
A clove hitch and binder on the taut part of the rope. The ropes must be taut and all slack removed in order to secure the appliance in a fixed position.
Remove all slack in the safety chain and secure it to a substantial object, if one is close enough. Is a rope always needed to secure the multiversal?
3.3.5 E.
The safety chain alone should never be relied on to secure this appliance. A rope is needed.
The use of two hose lines to supply the Multiversal Nozzle is recommended. When two hoses are used, bring them straight back a distance of how many feet before making any sharp bends or turns inthe hoselines?
3.4.2
15 feet from the siamese, parallel to each other, before making any sharp bends or turns in the hose lines.
If only one hose line is used, bring it straight back for how many feet before making any sharp bends or turns inthe hoselines?
3.4.3
15 feet before making any sharp bends or turns.
When the Multiversal Nozzle is being operated in the portable position, do not move the ground base or the 15 feet of supply hose that is closest to the unit, unless what is done?
3.4.4
The water supply is shut down.
When used in the portable ground base, the unit should not be operated at more than 800 gallons per minute with any type of straight stream or Fog Tip.
A. In order to avoid operating at more than 800 gallons per minute with straight stream tips, the following pressures shall not be exceeded:
10-75
3.4.5
1¼” tip - not more than 100 psi
1½” tip - not more than 70 psi
2” tip - not more than 50 psi
When the supply lines feeding the Multiversal Nozzle are long, so that communication with the engine company chauffeur may be difficult, what can be inserted to assure that proper pressures are maintained?
3.4.6
A single gate one length from the nozzle. A member can be stationed at these gates to assure that proper pressures are maintained.
After each use, the spikes in the portable ground base shall be inspected. If the flats on the end
of the spikes exceed ____ in diameter, the spikes must be sharpened or replaced in accordance
with the instructions contained in the Manufacturer’s Manual, which has been issued to units.

When operating the Multiversal Nozzle from its apparatus truck mount, what should be used to supply water to it?.
4.7
When operating the Multiversal Nozzle from its apparatus truck mount, a 50’ length of hose
should be used. This makes it easier to lift the nozzle from its base if it becomes necessary to
cover an arc greater than 180 degrees.
If for any reason units are unable to secure the Multiversal Nozzle in the portable ground base
or the apparatus truck mount, the Multiversal shall be taken out of service and who shall be notified?
7.3
The Repairs and Transportation Unit shall be notified.
