GENERAL DESCRIPTION
The MAXIKITE Image Intensified Weaponsight is a compact light weight passive night vision device which may be used in a hand held surveillance role or mounted to a weapon and zeroed using its adjustable graticule.The MAXIKITE weaponsight is a combination of the fully proven and successful KITE (MK IV) weaponsight and an afocal lens assembly. MAXIKITE can be supplied as a complete weaponsight or an adaptor assembly to up-grade existing KITE weaponsight variants. If an up-grade to MAXIKITE is required, PPE recommend the conversion is performed by suitably qualified personnel in accordance with the unit maintenance instructions contained in this handbook.
The sight consists of four main assemblies, the marikite adaptor, the objective, the magnifier, and the mounting bracket. Industrial nylon has been used to mould the maxikite adaptor, objective and magnifier assembly housings.
The magnifier assembly contains the eyepiece optical elements, an illuminated aimpoint graticule, an image intensifier tube (IIT) and two 1.5 V batteries. The OFF/ON/GRAT switch, graticule brightness control and all associated wiring are also contained within the magnifier assembly.
The sight is supplied in a transit case which also contains a carrying pouch, lens cleaning cloth, batteries, user handbook, screwdriver, 'C spanner, objective clamp ring and objective clamp ring tool.
The mounting bracket assembly is constructed of aluminium and provides the mounting interface for use on sniper rifles, heavy machine guns and shoulder launched/crew served anti-tank weapons.
The MAXIKITE weaponsight sight has a x6 magnification and provides a high resolution image for effective observation and accurate weapon aiming at long range targets. In addition the sight has been designed for use with the AFV Crewmans Helmet, General Service MK IV Helmet, S6 Respirator, NEC Clothing and Military Spectacles.

GENERAL
The weaponsight is a sealed instrument and must not be tampered with or maintained in excess of the instructions contained in this handbook. User/Unit Maintenance is limited to cleaning, pressure testing and desiccation, and replacement of the maxikite adaptor, batteries, ND filter assembly, rubber eyeguard, carrying pouch, transit case, lens cleaning cloth, user handbook and screwdriver.
CLEANING
Dust on the optical surfaces should be removed with the cleaning materiel provided. If there is mud or grit on the ND filter, objective lens or eyelens, it should be first be removed with clean water. Dirt is removed using a moistened lens tissue, taking care not to trap abrasive matter between the tissue and the glass. Soap or a mild detergent may be used to remove greasy stains or smears. Do not use Petroleum Spirit or other solvents. Lightly polish the optical surfaces using clean dry lens tissue.

PRESSURE TESTING & DESICCATION
Pressure testing and desiccation of the weaponsight (assuming a controlled storage environment) is to be carried out at least once a year in all climates. In the absence of a controlled storage environment (no temperature or humidity controls), pressure testing and desiccation of the weaponsight is to be carried out at least twice a year in temperate climates and four times a year in tropical climates.
Individual red coloured desiccating (purging) screws, complete with bonded seals, are installed to the underside of the Objective Housing and to the base cover of the Magnifier Housing. Either one of these desiccating screws, complete with its bonded seal, may be temporarily removed to enable pressure testing and desiccation of the Kite MK IV weaponsight to be carried out. A single purging screw is provided to enable pressure testing an desiccation of the maxikite adaptor. The remaining two desiccating screw located at the interface end of the maxikite adaptor are provided to enable the air gap between the adaptor and weaponsight to be purged. Pressure testing is to be carried out using clean Dry Nitrogen (t MIL-N-6011 specification) and a Leak Detector Kit, NSN V7/6685-99-9e -5713 (or equivalent). The maximum permitted leak rate at an interni pressure of 2.5 lbf/in2 is 0.02 lbf/in2 in 10 minutes.Desiccation can be performed by flush purging or using a Dehydrate Desiccant, Electric, Series 3 MK. 3, NSN V7/4440-99-964-8511 (or equivalent)
NOTE
The weaponsight can be used as a standard KITE MK IV weaponsigt by using the objective clamp ring tool to install and fully tighten tb objective clamp ring, and installing the ND Filter Assembly which at provided as part of the cased store.Clean optical surfaces of maxikite adaptor and objective assembly using lens tissue moistened with Isopropyl Alcohol.Using 'C Spanner, install replacement maxikite adaptor (2) to objective assembly (3) and install MAXIKITE ND Filter assembly (1).

BATTERIES
Release the captive screw (7), open out the battery cap (8) and remove the batteries (6).
Insert two serviceable 1.5 volt batteries (6), with their positive ( + ) contacts forward, into the battery compartment (5).Close the battery cap (8) and secure using the captive screw (7).
ND FILTER ASSEMBLY
The ND filter assembly (1) is removed by manoeuvring the rubber strap from around the maxikite adaptor (2) and pulling away.
RUBBER EYEGUARD
The rubber eyeguard (10) is removed by carefully prising it out of the location recess in the eyepiece (9).
