It is quite a straightforward job to convert the BHX2500 from blower to vacuum model, though it is important to do it correctly.
But remember, before you undertake any work on this machine or other powered hand-held kit, you must make sure that it is switched off. It is also wise to pull the spark plug connectors off the spark plug.
You should sit the blower on a bench with the blower pipe pointing away from you. The impellor should be on the left-hand side. Loosen the screw at the top of the impellor guard. This guard is hinged and should open downwards.
Now take the vacuum pipe (straight piece) and align the arrow on it with the circle on the edge of the impellor housing. Insert the vacuum pipe and turn it until the arrow on the pipe is aligned with the triangle further along the edge of the impellor housing. This locks the pipe into place.
Next, open the fastener of the dust or collection bag. Insert the elbow pipe (the one with a 90 degs bend in it) into the bag and push it out through the bag's entry hole. Then zip up the bag again. Finally, connect the elbow pipe to the vacuum pipe. Never try to connect the elbow direct to the blower's impellor.
Run your pre-start checks, including the spark plug connection, and start the machine as you would in its blower mode. The dust bag should be carried over your shoulder and adjust the strap so that it is comfortable. Ensure that the dust bag is not twisted and pull the trigger, as you would with the blower, to commence collection.
When operating the BHX2500, the main handle should always be uppermost. Never suck up fuel, lit cigarettes, large wood chips, metal, glass or stones. These can, at least, cause the machine to fail and at worst can cause fire.
Always remember to empty the bag as soon as it is full — not just because the performance can be reduced but also because overfilling can present a fire hazard. The bag is emptied through the zipped opening.
One final thought — when you are converting the unit back to a blower, ensure that the screw holding the impellor guard in position is fully tightened. In fact, checking and retightening this screw should be part of your pre-start checks.
