If the machine falls from any height, is wet, or has any other damage that could affect the technical state of the machine, stop the operation and immediately send the machine to the service center for inspection and repair.
LP35 + 3. STARTUP AND OPERATION 3.1. Installing and removing the handle Install the handle by using the adapter as shown in Fig. 1. The handle can be installed from the opposite side of the machine to allow working in places hard to reach or using the machine by a left-handed person.
LP35 + 3.2. Installing, removing, and operating the annular cutter Unplug the machine from the power source, raise the safety guard, and then rotate the handle to the left (1, Fig. 2) to access the set screws 2. Next, wear protective gloves, insert the supplied pilot pin into the annular cutter (3), and then use a clean and dry cloth to wipe the arbor and cutter.

LP35 + Fig. 3 shows how annular cutters operate. As the cutter penetrates the workpiece, the pilot pin recesses into the arbor and tightens the spring. As a result, after the cutter goes through the entire thickness, the slug core is expelled from the cutter. Arbor Spring Annular cutter...
LP35 + 3.3. Preparing Before beginning, clean steel parts, including the arbor, from anti-corrosion coating used to preserve the machine for storage and transport. Install the handle as described before. Based on the hole size desired, select the proper annular cutter or drill bit with a 19 mm Weldon shank.

LP35 + Vertical drilling Inverted drilling CORRECT ✓ Horizontal drilling INCORRECT Maximum possible twist of the strap Fig. 5. Protecting the machine from falling by using the safety strap Rotate the handle to the left to place the pilot pin (drill bit) above the workpiece. Fill the coolant bottle (not included) with a cutting fluid.
LP35 + 3.4. Drilling Start the motor with the green MOTOR button, and slowly rotate the handle to the left to lower the tool to the workpiece, and begin drilling. When using annular cutter, drill holes in one pass. When the annular cutter goes through the workpiece, the slug core is expelled from the cutter with a significant force.
LP35 + 3.5. Replacing the motor brushes Check the condition of the carbon brushes every 100 operation hours. To do this, unplug the machine from the power source, and unscrew the cover (1, Fig. 6). Next, unscrew the pressing plate (2), and then remove the brush holder (3) and the brush (4). If the length of the brush is less than 5 mm (3/16’’), replace both brushes with new ones.
LP35 + 4. ACCESSORIES 4.1. Coolant bottle with nozzle Capacity of 250 ml (8 oz). Part number: PJM-000003 4.2. HSS quill assembly Allows you to drill holes to a depth of up to 25 mm (1’’) by using HSS annular cutters or twist drill bits with a 19 mm (3/4’’) Weldon shank.

LP35 + To install the assembly, unplug the machine from the power source, raise the cover, and then rotate the handle to the left (1, Fig. 7) to lower the standard TCT quill assembly as much as possible. Next, remove the handle, use pliers to remove the retaining rings (2), and then push out the shaft (3) by 16 mm (10/16’’), which will expel the TCT quill assembly (4).
