Frequently Asked Questions - AHS 4-16 BOSCH

What safety precautions should be taken before using the Bosch AHS 4-16 hedge trimmer?

Before each use, check that the blades, screws and protective devices are in good condition. Wear closed-toe shoes, long trousers, protective gloves and safety glasses. Make sure no person or animal is within 3 meters. Never work in rainy weather or on wet hedges.

How to start and stop the AHS 4-16 hedge trimmer?

To start, keep the On/Off switch on the rear handle pressed, then press the switch lever on the front handle. To stop, release both switches. The blades continue to move for a few seconds after stopping.

What is the maximum cutting height and how to trim a straight hedge?

The cutting length is 420 mm and the blades can cut branches up to 16 mm thick. For a straight cut, stretch a guide line along the hedge at the desired height. First trim the sides, then the top, preferably from bottom to top.

What are the recommended trimming intervals for different types of hedges?

For leafy hedges, trim in June and October. For conifers, trim in April and August. Fast-growing hedges can be trimmed every 6 weeks from May.

How to clean and maintain the hedge trimmer blades?

After each use, unplug the appliance and clean the blades with a soft brush. Apply maintenance spray to lubricate and protect against corrosion. Wear gloves when cleaning. Regularly check the tightness of the blade bar screws.

What to do if the hedge trimmer does not work or works intermittently?

First check the power supply (outlet, fuse). If the cable is damaged, replace it via Bosch service. If the problem persists, contact customer service. Do not attempt repairs yourself.

How to store the hedge trimmer after use?

Place the blade guard on the blades. Store the appliance in a dry and closed place, out of reach of children. Do not place any objects on top and ensure the ventilation slots are clean.

What accessories are available for the AHS 4-16 model?

Compatible accessories include: blade guard (ref. F 016 800 165), collecto 40 (ref. 2608005112), safety glasses, gloves, maintenance spray and catch cloth. Always use Bosch genuine parts.

Why do the blades heat up abnormally?

Excessive heat may be due to dull or chipped blades or insufficient lubrication. Have the blade bar sharpened or replaced by a professional. Lubricate regularly with maintenance spray.

For Your Safety

Warning! Switch off, remove plug from mains before adjusting, cleaning or if cable is cut, damaged or entangled.

The blades continue to move for a few seconds after the hedgecutter is switched off. Caution! Do not touch the moving blades.

Electrical Safety

Your machine is double insulated for safety and requires no earth connection. The operating voltage is 230V AC, 50Hz (for non-EU countries 220V , 240V as applicable). Only use approved extension cables. Contact your Bosch Service Center for details.

Extension cords/leads should only be used if they comply with H05VV-F or H05RN-F types.

It is recommended for increased electrical safety to use a Residual Current Device (RCD) with a tripping current of not more than 30mA . Always check your RCD every time you use it.

For products not sold in GB:WARNING: For safety, it is essential that the mains plug 6 attached to the machine is fitted to the power supply cable 9 as shown.

The couplings of connection leads must be protected against splashes and the coupling sockets on the leads must be made of rubber or coated with rubber.

Fixing means for the connection leads must be used. The connection lead must be inspected for signs of damage at regular intervals and may only be used if in perfect condition.

If the supply cord is damaged, it must be replaced by a Bosch Service Centre.

Products sold in GB only: Your hedecutter is fitted with an approved 13 A (BS 1363/A) electric plug and is protected by a 13 A fuse (ASTA Approved to BS 1362).

If the fitted plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorized customer service agent.

The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a 13 A socket elsewhere.

Fit handle guard as shown.

Starting and Stopping

Starting:

Press and hold rear switch lever 4. Squeeze any front lever 3.

Stopping:

Release any of switch levers 3 and 4.

C D E Tips on Cutting

Hold the hedgecutter away from yourself using both hands. Stand in a secure and stable position.

Position the extension cord over your shoulder to the rear and ensure that the cord is behind you at all times during cutting. Never place the cable over the hedge, where it could easily be cut by the blades.

Cut stems upto 16mm in thickness. When cutting, move steadily along the line of cut, so that stems are fed directly into the cutter blades. The double edge of the cutting blade enables cutting to either direction, or with a side to side motion.

Cut the sides of the hedge first, then the top.

To keep the sides flat, cutting upwards with the growth is recommended. Younger stems tend to move outwards when cutting them from top to bottom, resulting in shallow patches or holes in the hedge.

To reach a level finish, fasten a piece of string along the length of the hedge at the required height and use as an alignment guide. Cut the hedge just above the string.

Take care to avoid cutting into objects such as wire, which could cause damage to the cutting blades and the drive.

Recommended cutting/trimming times:

• Cut hedges with deciduous leaves in June and October.
• Cut evergreen hedges in April and August.
• Cut conifer and other fast growing shrubs approx. every six weeks from May onwards.
• Shaping hedges should be cut to achieve a form as shown in figure.

Maintenance

Before any work on the machine itself, pull the mains plug.

Note: To ensure long and reliable service, carry out the following maintenance regularly.

Check for obvious defects such as loose, dislodged or damaged blade, loose fixings and worn or damaged components.

Check that covers and guards are undamaged and correctly fitted. Carry out necessary maintenance or repairs before using.

If the hedgecutter should happen to fail despite the care taken in manufacturing and testing, repair should be carried out by an authorized customer service agent for Bosch garden products.

For all correspondence and spare parts orders, always include the 10-digit part number (TYP) from the nameplate of the machine!

Blade Maintenance

Before any work on the machine itself, pull the mains plug.

Wear gloves when handling or cleaning the cutting blade.

Always clean the cutting blade after operation and lubricate with protective spray. During longer cutting jobs, we recommend periodically lubricating the cutting blade with protective spray.

Visually check the condition of the cutting edges of the cutting blade 1. Check tightness of blade bolts.

Ensure that the blade is covered with the blade guard 7 supplied.

Cleaning/Storage

Clean the exterior of the machine thoroughly using a soft brush and cloth. Do not use water, solvents or polishes. Remove all debris, especially from the ventilation slots 5.

Store the hedgecutter in a secure, dry place out of the reach of children. Do not place other objects on top of the machine.
