After unpacking your grenade, handle it exactly as you would a loaded gun. Hold the body in one hand with the cartridge chamber pointing away from you, carefully unscrew the chamber without letting any part of the hand covering the flash hole in the side and end. The chamber may now be inspected.
Examine just inside the top of the threaded receiver. If the tip of the firing pin is protruding, the mechanism will have to be cocked before loading the cartridge.
If only the firing pin hole is visible then the grenades mechanism is cocked. Use the thumb to hold the lever hard in, the ring pin may be pulled and the lever released.
The lever will move away from the body and then back again as the delay mechanism works to remain slack but still attached to prevent loss. There will be a delay before the firing pin operates, this delay is set during the manufacturing process and cannot be altered in the field. It is important that this dry firing is done every time the grenade is used for the fire time each day to make sure that the delay and the mechanism is still working well. If it is not operating as it should do not use it but return the device for servicing.
For storage, the firing pin should be released to take the strain off the spring and prolong the life of the device. It will be found after release that the ring can be replaced in the normal position under the lever to prevent loss.
Cocking/Arming the Grenade:
Remove the ring pin and cartridge chamber. Place the grenade base down on a table, grip the body of the grenade with one hand and with your thumb covering (but not holding down) the lever. During the cocking/arming process the lever will move away from the body of the device and then back again (flush). THis must be allowed to happen and when the grenade is fully cocked the lever must be firmly held in and the ring replaced. Do not for the lever in against the body of the device, only hold it in when it goes back of its own accord, only at this point is the mechanism fully retracted.
The cocking rod/or arming tool will be found to have a depression In the end. Carefully place this depression on the tip of the firing pin in a vertical position with the knob in the palm of your hand, press down on the firing pin allowing the fingers of the pressing hand to enshroud the body and from extra guidance to ensure a straight line push.
Spring pressure will be felt at first, but then an extra resistance will be felt when overcoming the delay mechanism. Pressure must be steady and progressive at this time and must continue until the lever drops back against the grenade body and can be firmly trapped there by the thumb, at which time the cocking tool can be removed and the ring pin re-installed with the ring on the left when looking at the lever (for the right handed users).
After some practice with the grenade on the table you will find that you can do the whole operation in your hands. Always make sure that you press in a straight line with the tool properly placed on the pin and be sure to trap the mechanism at the very bottom with the lever.
If you do not get it quite right, quickly remove the Tool and allow the mechanism to fire off then start the process again. Always do a dry fire at the beginning of each period of use to determine that the delay mechanism is working correctly.
Types of cartridges to use:
The chamber is designed to take a 12 bore blank (saluting blank). These are generally used outdoors. There are adaptors available to be used for timmed 0.38/9mm blanks possibly indoors at the discretion of the instructor. After firing, the cases may be expelled by inserting the cocking tool through the small hold in the end of the chamber. Plastic extrusions from the saluting blank may have to be eased back through the flash hole prior to ejection.
To load, simply place the chosen cartridge into the chamber and invest the cocked body over the chamber, screw up finger tight only, keeping the fingers away from the flash hole. Doing this operation with the grenade inverted makes sure that the cartridge stays in place and keeps that end away from the user's face.
THE GRENADE IS NOW IN A LIVE CONDITION AND MUST BE HANDLED WITH GREAT CARE UNTIL USED
For the right handed use, grip the grenade with the pad of the hand at the base of the device, covering and pressing hard onto the lever with the fingers and thumb wrapped tightly round the body, the cartridge chamber at the top and the ring pin towards you above the thumb.
The ring is now in the best position for withdrawal by the index finger for the left hand. Hold on tightly until the moment that the pin is drawn. Do not try to release the lever to remove part of the delay (or cook off the genade) before throwing. The delay is already short enough and is designed to prevent throw back.
WARNING: If any movement is felt in the lever whilst it is till in your hand then you have not held on to it tight enough and it is about to go off. Get rid of the device in a safe direction and quick as possible.
Having pulled on the ring, it makes good sense to glance down before throwing to make sure the pin has been completely removed.
The over arm bowl is the normal way of throwing for the greatest distance but this will depend on the circumstances and a simple lob through a window or doorway may be more sufficient.
Practice all of the operations before using a live blank. No harm will be done by dry firing and much can be learned from safety.
Care and Maintenance:
The grenade body should be wiped with a clean dry cloth after use in an un-cocked condition with the ring and pin removed. This will mean that the firing pin will stop any dirt entering the chamber through the firing pin hole. A slightly damp cloth may be used for stains on the body but do not allow any moisture to enter the firing pin hole and never try to lubricate any part(s), It does not need it and the timing unit may be affected. If in doubt, return the unit for servicing. It is not possible to service the unit without special tools. The cartridge chamber may be washed and dried thoroughly if the cartridges are using black powder.
Failure to explode may be caused by a poor cartridge, mechanical damage or the chamber not being completely screwed home.
In the event of a misfire, allow the grenade to lie where it is for at least five minutes. If nothing happens during this time, carefully pick it up at the base with the finger and thumb and drop it chamber first nto a reasonably hard surface from waist height. This will shock the mechanism and it may go off. If this still fails, allow another delay and then carefully unscrew the chamber while pointing it away from you using a leather glove and ear and eye protection.
If the cartridge appears to be well struck then it was probably a dud. Examine the firing pin to make sure the point is still intact and try to dry fire the device several times. If there appears to be a problem, return the grenade for servicing. If all appears well the grenade should be tried again. If it works on this occasion, the fault can be put down to a bad or faulty cartridge.
The superb versatility of this device now places endless scenarios in the hands of the instructor. During training sessions on the rifle or pistol range, the grenade can be used by the instructor to introduce a dimension of uncertainty, to put the trainee under pressure, to develop fast reactions. On the assault course they can be used to introduce some realism and stir the adrenalin, thus training the mind for handling other situations.
Squads learning house clearance, rapid intervention, hostage rescue and building take-over, can be thrown in a grenade or two for softening up purposes. When other squads are simulating the enemy, the excitement mouns and the training achieves far more realism with the benefit of better appreciation of the noise and confusion of the actual operation. The opportunity to handle such a device will give a boost to the confidence of the trainee.
