Hop Up Unit Adjustment

Hop Up Unit Cleaning

The Hop Up Unit adds a back spin to the BB to allow a longer flight path.

Before use please do so in a safe location and make sure nobody is behind

the target. When using different weight BBs you will have to make adjust-

ments. When not is use please turn the Hop Up Unit off.

How to clean the inner barrel.

Turn Hop Up Unit OFF - Disconnect Battery - Remove Magazine

1. Use the Angled end of the cleaning rod to push the BB backwards

and out through the Hop Up Unit.

2. Make sure to have the angled end facing down and silicone oil will

help loosen the BB.

NOTE: If you continue to fire the gun with a jam you will cause more

damage.

Cut the cloth or paper towel in the size as shown above. Fold the material to

fit through the loop. Adjust the length of the material to smoothly enter the

barrel. otherwise too much material will get jammed in the inner barrel and

can cause the hop up bucking to get out of place.

1. Spray silicone oil into the hop up chamber from the wagwell for 1 sec. and

fire 10-15 BBs to oil inner barrel and hop up parts.

2. Fire 2 shots with magazine removed to clear gun of BBs and disconnect

battery.

3. With a twisting motion gently push the cloth and rod down the barrel.

Repeat 2-3 times until clean.

NOTE: You can apply silicone oil directly to the cloth as well.

If there is too much oil in barrel the BB trajectory will be unstable.

Only use Echo1USA BBs into your Echo1USA Airsoft Rifle. The use of .12g or

‘low grade’ BBs will damage your Airsoft Rifle and VOID the warranty.
