• Do not operate any appliance with a damaged cord or plug or after the appliance malfunctions, or is dropped or damaged  in any manner. Contact the manufacturer at their customer service telephone number for information on examination, repair or adjustment.

• Avoid contacting moving parts.

• Do not use outdoors.

• Do not let cord hang over edge of table or counter.

• Do not place on or near a hot gas or electric burner or in a heated oven.

• The use of attachments not recommended or sold by the manufacturer may cause fire, electric shock or injury.

• To disconnect, ensure power switch is in “OFF” position, then remove plug from wall outlet.

• Do not use grinder for any purpose other than its intended use.

• lways place all lids in the correct position, as shown in the descriptive images in this manual.

• NOT DISHWASHER SAFE.

ENVIRONMENTAL RECOMMENDATIONS
Dispose of filters and coffee grounds in an organic waste container or compost heap where available. If not available, filters and grounds may be disposed of in normal household waste. Please recycle all packaging and parts responsibly.
MOTOR OPERATION AND REST ALLOWANCE
A maximum of 225 grams or 8 ounces of coffee beans may be placed into the bean hopper. For proper use, operate this appliance  for less than 90 seconds per time with a minimum of 90 seconds of rest time maintained between two continuous cycles. The grinder can not work for 6 minutes continuously within 10 minutes, and it must rest for 30 minutes if the working time exceeds 6 minutes.
GLASS GROUNDS CONTAINER CAPACITY
To ensure correct operation, avoid filling the glass grounds container past the top marker as indicated below. Overfilling the glass grounds container can clog the dispensing spout and cause the motor to jam.

Cleaning Your Grinder

Basic Cleaning
Make sure to unplug the grinder before cleaning. Wipe the inside surfaces of the bean hopper with a moist cloth at least once a week to avoid a buildup of the coffee oils, which can cause discoloration. When needed, you may also clean the exterior surfaces with a moist cloth, wiping dry. Do not use any cleaning agents to clean the interior or exterior of the coffee grinder. Do not wash any grinder parts in the dishwasher. Do NOT use rice to clean your grinder.
Maintenance Cleaning
We recommend cleaning the inside of your grinder every 3-6 months, depending on how frequently you grind coffee and the type of coffee you’re using. Darker roasts are typically oilier and tend to stick to the inside of the grinder more easily. If you do not clean your grinder regularly, you may find that it negatively impacts the flavor of your ground coffee. The inside of your grinder can either be cleaned manually or automatically by using a dedicated coffee grinder cleaning product.
Manual Cleaning
Refer to our Burr Replacement instructions on our website to learn how to disassemble your grinder. For best results, use a soft brush and a vacuum cleaner to clean the grinding chamber.
Automatic Cleaning
A grinder cleaning product will remove coffee oils and particles stuck inside the grinder without disassembly. Purchase a grinder cleaner product from your preferred retailer such as Biocaf Coffee Grinder Cleaning Tablets by Urnex. The product you choose should be suitable for burr grinders. To use, follow the manufacturer’s directions on the packaging.

Use Fresh Beans
The fresher the grind, the better. We recommend grinding your coffee beans right before you brew, and grinding just the amount you need. If you do grind more, you can store the grounds in your grinder’s glass grounds container with storage lid.
Grind Size
How coarse you’ll need to grind your beans depends on your brewing method; when brewing on a Macmaster, you’ll want your beans ground to medium-coarse. See our chart below for a range of brewing methods.
Dial In Your Grind
Coffee grounds that are too fine can produce an over extracted cup of coffee. Too coarse, and your coffee may be weak or flavorless. Use our chart below as a starting point, but experiment with small adjustments to find the grind that’s perfect for your palate.
Keep it Clean
If you don’t use your grinder daily, you may want to clear out old grounds before grinding a fresh batch. Pre-grind a small amount of coffee first and discard.
Water
If it tastes good to drink, it will make good coffee. We recommend fresh tap, filtered, or bottled water. We do not recommend using reverse osmosis filtered water or distilled water, as it can damage the brewer’s boiling element and lacks minerals necessary for making great coffee.
What’s in the Cup
The coffee-to-water ratio we recommend is the approved industry standard, but your taste preferences may vary. If your coffee is too strong, add hot water to your finished cup. If it’s too weak, DO NOT add more coffee – instead, try a different coffee roast or growing region.
REPLACEMENT PARTS
Replacement parts are available through many retailers, online at www.moccamaster.com, or through Consumer Relations at 855.662.2200.

Adjusting Your Grind Settings

Grind Setting Details
The adjustment knob on the KM5 Coffee Grinder allows you to produce coffee grounds that range from fine (1) to coarse (9). When grinding for a Macmaster coffee brewer, we recommend starting at the ECB approved setting of 5. We suggest not grinding below 5 for your Macmaster as a finer grind size may negatively affect the flavor of your brew and the performance of your machine. The Importance of Grind Size
Your grind size and your water-to-coffee ratio are the first steps to perfect coffee. To find your ideal grind, make minor adjustments to the grind setting and taste how it changes the flavor of your coffee. Your grind size will affect your final extraction – the amount of coffee solubles in your cup. Learn more about how to dial in your perfect grind online at www.moccamaster.com.
Recommended
Coffee-to-Water Ratio
The industry standard for optimal flavor is 2 tbsp. of ground coffee to every 6 oz. of water – or 55 grams of ground coffee per liter. Getting Started
For first use, set the adjustment knob to 5. On subsequent use, always activate the power switch before adjusting the grind setting. This allows the burrs to clear any partially ground beans that may be present from previous use. If bean remnants are trapped in the burrs, adjusting the grind setting without activating the grinder may cause the motor to jam. Step 1.
Activate the grinder by holding the Power Switch (D). Step 2.
With the grinder running, adjust the grind setting by rotating the
Adjustment Knob (J) clockwise or counterclockwise.

• Turning the knob clockwise will produce a finer grind.
• Turning the knob counterclockwise will produce a coarser grind.

• For more information about grinder use and functionality, see the Important Safeguards section in this manual.

KM5 Grinding Guide

Step 1.
Place Glass Grounds Container Lid (F) in position. Place Glass Grounds Container (E) underneath the Dispensing Spout (H).
Fill Hopper (B) with coffee beans – up to a maximum of 225 grams or 8 ounces. Place Hopper Lid (A) on top of the hopper. Step 2.
Insert Power Plug (C) into a grounded outlet. Press and hold the Power Switch (D) until you have ground the desired amount of coffee.
Note: Do not fill the glass grounds container past the top marked line (approx. 110 grams). Allowing the container to overflow may result in jamming the grinder motor. Step 3.
Remove the Glass Grounds Container from underneath the Dispensing Spout and remove the Lid. Step 4.
Measure or weigh your grounds and transfer to your prepared brew basket or coffee brewer. If you have leftover grounds, seal the grounds container with Storage Lid (G).
You’re ready to brew great coffee!
