What is Greasing and Why is it Important?
If you’re wondering how to grease a Hilti hammer drill, it’s important to first understand what greasing is and why it’s necessary. Greasing involves lubricating the internal moving parts of machinery or equipment to reduce friction and wear. In the case of a Hilti hammer drill, this includes the gears, bearings, and other components inside the tool.
Over time, these parts can become dry or worn, which can cause the tool to perform poorly or even break down completely. By greasing the hammer drill regularly, you can ensure that it operates smoothly and efficiently, while also extending its lifespan. To grease a Hilti hammer drill, you’ll need to use a special grease designed for power tools and follow the manufacturer’s instructions carefully.
This will typically involve disassembling the tool, applying grease to the appropriate parts, and reassembling everything properly. With regular greasing and maintenance, your Hilti hammer drill can continue to serve you well for years to come.
Definition of Greasing
Greasing is the process of applying a lubricant to machinery to reduce friction. It involves the use of specific lubricants made to withstand high levels of heat, pressure, and friction. Greasing is a crucial maintenance procedure that protects machinery from wear and tear.
By lubricating the moving parts of your machines, you reduce the risk of friction, which can cause heat, corrosion, and damage to your equipment. Regular greasing ensures that you reduce the need for costly repairs and replacement of parts. It also prolongs the lifespan of your machinery, as well as makes them operate more efficiently.
Greasing should be done at specific intervals, as advised by the manufacturer. It is also essential to use the right type of grease for your machinery to ensure it performs at its optimal level. Overall, greasing is a crucial aspect of keeping your machinery in good working condition, and it should be taken seriously to prevent costly downtime.

Importance of Greasing a Hilti Hammer Drill
Greasing a Hilti hammer drill is important to maintain its optimal performance and prolong its lifespan. Greasing is the process of applying lubrication to the moving parts of the drill, such as the gearbox and the hammer mechanism, to reduce friction and prevent wear and tear. Without proper greasing, the drill’s components can become damaged, leading to malfunctions or even complete breakdowns.
Additionally, greasing can help prevent rust and corrosion, which can further damage the drill’s components. Regular greasing, as recommended by the manufacturer, should be a routine maintenance task for any power tool user. By taking the time to grease your Hilti hammer drill, you’ll ensure that it runs smoothly and safely, and that it’ll last for years to come.
Tools Needed to Grease a Hilti Hammer Drill
Learning how to grease a Hilti hammer drill is essential to maintain its optimal performance and prolong its lifespan. Before you start the greasing process, make sure to prepare the necessary tools such as a grease gun, lithium or molybdenum grease, and a clean rag. First things first, locate the grease fittings of your hammer drill, which come in two types: the zerk fitting and the screw-on fitting.
If your drill has a zerk fitting, use the grease gun to inject the lubricant into the fitting while applying pressure until it overflows. On the other hand, if it has a screw-on fitting, unscrew the protective cap and apply a liberal amount of grease onto the exposed threads. Remember to wipe off any excess grease and to keep the fittings clean to prevent any dirt or debris from accumulating.
By regularly greasing your Hilti hammer drill every three months or after 50-70 hours of use, you can ensure that it runs smoothly, minimizes wear and tear, and avoids costly repairs.
List of Required Tools
If you’re planning to grease your Hilti hammer drill, there are some tools that you’ll need to have on hand before getting started. First and foremost, you’ll need a can of Hilti grease. This is a specific type of grease that’s designed to work specifically with Hilti tools, so it’s important that you don’t substitute it for a different kind of grease.
You’ll also need a grease gun to help you apply the grease to the drill. It’s a good idea to have a rag or two on hand to help you wipe up any excess grease that may spill out during the process. Finally, you’ll need a wrench to remove the end of the drill in order to access the parts that need to be greased.
Once you have all of these tools and your grease ready, you’ll be ready to begin the process of greasing your Hilti hammer drill for optimal performance.
Steps to Grease a Hilti Hammer Drill
If you need to grease your Hilti hammer drill, don’t worry, the process is pretty straightforward. First, make sure your drill is turned off and unplugged, then remove the chuck by loosening the retaining screw. Once you have the chuck off, you can remove the grease nipple from the gearbox housing.
Use a grease gun to apply the recommended amount of grease to the gearbox. Be sure to use the type of grease recommended by Hilti for your specific model of drill. Slowly release the pressure on the grease gun to avoid overfilling the gearbox.
Once you’ve finished greasing the gearbox, replace the grease nipple and chuck, and you’re good to go. Be sure to grease your drill regularly to keep it running smoothly and prevent damage to the gearbox. By following these simple steps, you can keep your Hilti hammer drill in top condition for years to come.
Step 1: Preparing the Drill
If you own a Hilti hammer drill, it’s essential to keep it well-maintained to ensure maximum performance and longevity. One crucial aspect of maintenance is to regularly grease your drill. To do this, you’ll need to follow a few simple steps.
Firstly, ensure that the drill is switched off and unplugged from any power source before starting. Next, remove the chuck from the drill and clean it thoroughly with a cloth to remove any dirt or debris. Once it’s clean, apply a sufficient amount of Hilti grease to the chuck threads and reattach it to the drill.
Remember to wipe off any excess grease to prevent it from attracting dust and dirt. By following these simple steps, you’ll be able to keep your Hilti hammer drill running smoothly for years to come.
Step 2: Applying the Grease
When it comes to greasing a Hilti hammer drill, applying the grease is the second step in the process. Once you have cleaned the drill thoroughly, it is time to take the grease and apply it to the drill’s grease fittings. To do this, you will need to take your grease gun and attach it to the fitting.
Squeeze the trigger on the grease gun and fill the fitting with grease. You will need to fill the fitting until you see the grease start to come out of the sides of the fitting. This ensures that the fitting is thoroughly lubricated and will help keep your drill running smoothly for a long time.
It is important to note that you should not over-grease the fitting, as this can cause problems with the drill’s performance. So, take your time and make sure that you fill the fitting just enough to keep it well-lubricated. By following these simple steps, you can ensure that your Hilti hammer drill stays in great condition and performs at its best.
Step 3: Reassembling the Drill
Now that you have successfully removed the old grease from your Hilti Hammer Drill, it’s time to put it back together. Before reassembling, take a moment to inspect all the parts for any damages or signs of wear and tear. If anything appears damaged, it will need to be replaced.
Once you are satisfied that all parts are in good condition, apply a thin layer of lubricant to all moving parts, such as the chuck and gears. Make sure to use the correct lubricant, as recommended by the manufacturer. Once you have applied the lubricant, reassemble the drill in the reverse order that you disassembled it.
Double-check that everything is in place before tightening screws and bolts. Once complete, turn your drill on and let it run for a few seconds to distribute the grease evenly. Your Hilti Hammer Drill should now be ready for use! Remember to maintain regular greasing to keep your drill in good working order.
