1. Fire cannons should be used within the pressure range.
2. The integrity and operational flexibility of the gun should be checked frequently. If the fasteners are loose, they should be repaired in time to keep the gun in good use.
3. When shooting water, loosen the locking screw, adjust the spraying direction and angle of the gun, and then increase it to the pressure used.
4. Turn the jet adjustment ring to transform the tributary of the water into flowering, or convert the flowering to direct current.
5. After each use, spray water for a period of time, and then drain the water from the gun.
6. Lubricating parts of the cannon should be frequently lubricated to ensure flexible rotation.
7. When spraying, never stand in front of the muzzle.
8. Cannons cannot be used to extinguish live equipment to avoid electric shock.
9. In non-working state, the gun should be placed horizontally and covered with a rainproof cloth.
