Power cord grips used in this product: Type “Y”.
Tool build quality: Class II
Charger tool build quality: Reinforced insulation

 Avoid the risk of electric shock or severe injury. When the power cable gets damaged it should only be replaced by the manufacturer or at a  Authorized Service Center. The build quality of the electric insulation is altered if spills or liquid gets into the tool while in use.
Do not expose to rain, liquids and/or dampness.
Before gaining access to the terminals all power sources should be disconnected.

Power Requirements

 Tools with double insulation are equipped with a polarized plug (one prong is wider than the other). This plug will only fit in the right way into a polarized outlet. If the plug cannot be introduced into the outlet, reverse the plug. If it still doesn’t fit, call a qualified electrician to install for you a polarized outlet. Do not alter the plug in any way. Double insulation eliminates the need of both a grounded third power cord with three prongs or a grounded power connection.  When using an extension cable, verify the gauge is enough for the power that your product needs. A lower gauge cable will cause voltage drop in the line, resulting in power loss and overheating. The following table shows the right size to use depending on cable’s length and the ampere capability shown in the tool’s nameplate. When in doubt use the next higher gauge.

• It is safe to use only if the extensions have a built-in artifact for over current protection.
  AWG = American Wire Gauge. Reference: NMX-J-195-ANCE
   When operating power tools outdoors, use a   grounded extension cable labeled “For Outdoors Use”. These extensions are especially designed for operating outdoors and reduce the risk of electric shock.

Safety Warnings for Hammer drills / Drills / Drivers

Battery and Charger

•  Use only Truper Max chargers to charge the battery. Using a different charger may cause fire or injury hazard.

•  Use only batteries specifically designed for the tool. Different batteries could generate risk of injury or fire.

• Connect the charger to an alternating current (AC) supply only.

•  Do not use the charger outdoors.

• When charging, obey the “+/-“ polarity.

•  Never recharge a leaking battery or that is visibly damaged.

• Do not use batteries or a charger for purposes different that it was designed for.

• Do not modify the battery contacts or the chargers.
  Never expose the batteries to higher than 122 °F temperatures or direct sun light.

• Never expose the batteries to fire or impact. They could explode.

•  Batteries shall be kept away from metallic objects like clips, coins, keys, nails, screws or other type of object making contact with the terminals. It would cause a short circuit and burns or fire. They should be kept clean, dry and in good repair.

• Under extreme conditions the battery liquid could spill out. Avoid any contact. If an accidental contact happens clean with enough water. If the battery liquid comes into contact with your eyes, clean with enough water and immediately go see the doctor. Liquid expelled from the batteries could cause irritation or burns.

• Remove battery when not in use.

•  If the battery will be stored for long periods of time, keep an intermediate charge (40%) to maximize its useful life. Do not leave it completely charged for long periods of time, or leave it charging when not in use.

• Keep batteries away from children reach.

• Do not discard batteries together with household trash. Go to a specialized center for it’s recycling.

Choose the right bit

• Choose the right bit for the work piece. It reduces the risk of severe injury and makes the job easier.
• To work on metal or plastic, use bits suitable for metal. Sizes encompass a minimum of 0.05” and up to the chuck maximum capacity.
• On wood, use regular bits suitable for wood. In any case, to drill 0.25” or smaller orifices, use bits designed to drill on metal.
• Do not try using bits exceeding the chuck capacity.

Before operating the tool

• Take your time to assess the job to be done and double check you are paying attention to the necessary caution advices before starting to drill.
• Adjust correctly the bit into the chuck.
•  Before boring a wall, floor or ceiling, double check there are no hidden objects, like cables, power conductors or pipes.
•  Verify the switch is in the OFF position before inserting the battery. Otherwise it will start working unexpectedly, causing severe injuries.
•  Turn off and disconnect the tool before reversing the chuck rotation direction, as well as setting up or replacing a bit.
  Use auxiliary handles, if supplied with the tool. Loss of control can cause personal injury.

While operating the tool

• Hold the tool by it’s isolated surfaces designed for that purpose, especially when making jobs where the bit might contact hidden wiring. Contact with a power cable makes the metallic parts of the tool will be energized as well and produce a short circuit to the operator.
• Do not submit the tool to excessive loads.
•  If the bit gets stuck in the work piece, turn off the tool immediately. Then, remove the bit from the work piece. Do not try to remove stuck bits turning on and off the tool.
• Do not put excessive pressure on the tool to accelerate boring. Otherwise the bit will get damaged and the tool efficiency will diminish as well as it working life.
•  The largest the bit diameter, the reactive force is higher. The reactive force is higher causing loss of control over the tool. To prevent this possibility hold firmly the tool with both hands, and keep good footing while boring at 90°.
• Stay alert and ready to relax the force when the bit goes through the material. Sudden movements can break the bit or damage the tool.
•  Do not touch the bit or the orifices immediately after drilling. Wait for them to cool off to manipulate. Do not try to cool them with water or oil.
• Before leaving the tool aside make sure all the moving parts have come to a complete stop.
• Avoid setting the tool where there are particles and / or dust immediately after use. These can get absorbed inside the tool mechanism and damage the machine.
•  Wear hearing protectors when making jobs with a noise level higher than 85 dB.
•  Wear anti-dust mask and dust extraction equipment if necessary. Remember that working with materials like asbestos, leaded paint, additives, some types of wood, metals or minerals are highly toxic.
• Wear safety eyeglasses.

The cordless hammer drill is useful both for drilling holes with impact mode, as well as for screwing and unscrewing.

NOTE
In model MAX-20RS, battery and charger are sold separately.

Parts

Start Up

Loading the Battery

1. Plug in the charger in a 127 V~(The green light of the charging indicator turns on) power outlet.
2. Insert the battery into the charger sliding it as shown in the figure. The green light will turn off and the red light should come on.
   
   • When the battery is completely charged, the green light will be on and the red light will be off.
   • Disconnect the charger from the power once the charge is completed.
   • If the red light is blinking it signals a defective battery. Replace with a new one.
   • In case the green light is blinking it signal the temperature in the battery is lower to 32 °F or higher than 113 °F. Wait until the battery temperature is in the adequate level to be able to charge it.

General remarks for using the battery
The battery is shipped NOT CHARGED. It is necessary to charge the battery approximately 1 hour before being able to use it. The normal charge is 32 °F to 113 °F. When not in this level the charge automatically stops until reaching the right temperature. The normal temperature for discharge / work is 32 °F to 167 °F. If 167 °F are exceeded, the electronic control stops the tool energy until the temperature reaches the temperature optimum new level. When the battery is below the normal tension while working the tool stops working. Give the tool 15 minutes rest. In warm weather or after a long period of work the battery will get too hot to recharge. Allow the battery to cool down before trying to charge again.

Install and remove the battery

• To install the battery in the tool handle, align the battery unit with the rails on the inside of the tool handle and slide it into the handle until the battery unit is firmly inserted into the tool; check that it does not come off by itself.
• To remove the battery from the tool, press the release button (C) and firmly pull the battery out of the tool handle.
  

Bits or adaptors assembly

• Place the direction button in the locked position (center).

• Hold the handle firmly with one hand, and with the other hand turn the chuck counterclokwise for the jaws to loosen.

• Insert the bit until it stops or remove it whichever the situation.

• Turn the chuck tip clockwise to fasten the bit.

• The chuck has a lock that activates when turning the chuck. You will listen a click when the bit is set.
  

Direction of rotation

• To bore and screw release the switch and and press the direction button on the side where arrows point towards the chuck.
• To reverse the turn, and unscrew press it on the other side.
• The drill switch will get blocked if the button sits in the middle.
•  The first time you turn on the drill and after reversing rotation you might hear a click. This in normal and does not represent a problem.
•  To prevent damaging the tool, never reverse the rotation direction while the drill is running.
  

Speed selection

• The two speeds in the drill work in a similar manner to those used in cars.
• Low speed (1) will give a lot of torque (torsion power). Use this speed when starting to drill large orifices, be it wood or metal. This will prevent the bit to get stuck.
• High speed (2) has a reduced torque but lets the drill operate with higher revolutions per minute, that make the tool when in the drill function to bore faster lean metal or wood.

Change from hammer drill / drill / drivers

• To bore concrete, tiled floor or materials similarly hard, turn the function selection collar into the  IMPACT  ( ) position. The bit will strike and rotate atthe same time onto the material.
• To bore metal or plastic turn the function selection collar into the DRILL (  ) position to make the bit rotate against the material.
• For screw / unscrew turn the function selection collar to this position (  ) so the bit turns over the screw for better control.
   Do not try to drill metal, wood or plastic with the hammer drill in the IMPACT mode. Otherwise the tool efficiency would diminish and thebit tip will get damaged.
  

Torque Adjust

• To select the desired torque level to screw drive, turn the torque regulator until it matches the corresponding number with the upper mark: From 1 to 4 for small screws, From 5 to 9 for screws on soft materials, From 10 to 15 for screws on soft and hard material. On 16 to 21, for larger screws.
•  The torque level necessary depends on the type of screw to be used and the material onto which you are working. If in doubt use a lower torque and increase gradually until reaching the right one. An adequate torque prevents damaging the tool.
  

Turn On and operation control

• The switch allows selecting the adequate speed for each job. The more you push the switch the fastest the drill will run.
• The switch is also built with a braking function. When releasing the trigger, the drill will immediately stop and you will be able to use it as a manual screwdriver to give a screw an extra turn.
  

Screwing – Unscrewing

• It is recommended to first bore a “pilot orifice”; slightly longer and barely narrower than the measurements of the screw. This orifice will be the entry guide for the screw and will make it easier to tighten. When screwing near the edge of a work piece, a pilot orifice prevents the wood from cracking.
• Use the adequate type of tip for each screw head to prevent the screw from sticking over from the surface.
• If inserting the screw gets difficult, remove and try to bore a slightly longer or wider orifice. However keep in mind there should be enough material to fasten the screw. If you reinitiate the screwing operation in an already-made orifice, start threading it by hand. If still difficult to thread the screw (as with noble woods), try using lubricants like soap. Liquid soap is more useful.
• Always apply enough pressure on the drill to prevent the screw head to slide. It is easy that the screw head gets damaged, making it difficult to completely get inserted or even to remove it.

Additional recommendations

• Use the adequate speed for each job: do not try to bore at low speeds or to screw at high speeds.
• If the operation overloads the drill, take it out and repeat the operation applying less strength.
• Use low speeds to start bores where there is no support point; on plastic or metal; when screwing, boring ceramic or any other application that requires a high torque. Use high speeds to drill woods and using polishing devices.
• To get a longer drill duty life, use the variable speed control.

Drilling

• When trying to bore large diameter orifices it is better to start with a narrow bit and then replace it with the required size. This prevents overloading the drill.
• When drilling deep orifices remove the bit a little and regularly while boring to allow the shavings to be correctly expelled from the orifice.
•  If the bit gets stuck, immediately release the switch to prevent damaging the tool. Try to release the bit reversing the operation direction.
• Keep the drill aligned regarding the orifice. Ideally the bit shall enter the work piece perpendicularly. If the angle is changed while drilling, it could make the bit to break and block the orifice or causing personal injury.
